Machin series
Encyclopedia
The Machin series of postage stamps is the main definitive stamp
series in the United Kingdom, used since 5 June 1967. It is the second series to figure the image of Elizabeth II
, replacing the Wilding series
.
Designed by Arnold Machin
, they consist simply of the sculpted profile of the Queen and a denomination
, and are almost always in a single colour.
After four decades of service, the series has encompassed almost all changes and innovations in British stamp printing. This has been encouraging an abundant specialised philatelic
collectors' market and associated literature.
Arnold Machin's 1964 effigy of the Queen was replaced on British coins in 1984 by an older-looking effigy by Raphael Maklouf
, and then replaced again in 1998. However, the effigy on British stamps has never been updated, and the last proposals to these ends were rejected by the Queen herself.
figured a three-quarter photograph of the Queen by Dorothy Wilding
. The same effigy had appeared on commemorative stamp
s too. However, the Wilding design did not please some artists. In a letter of April 1961, Michael Goaman and Faith Jacques argued that it represented the Queen, but not the monarchy. They complained it embarrassed the commemorative stamps' designers because the photograph took up one third of the stamp's area and it imposed a perspective on a two-dimensional design.
Some new designs were discussed but concerns over the technical aspects (a photograph or a painting inspired by a photograph) delayed a full competition for artists until 1965. Postmaster General
Tony Benn
and artist David Gentleman
failed in their attempts to have the royal head replaced by the name of the country ("Great Britain" or "U.K."), but were permitted to explore temporary solutions to the commemorative head problems. This would of course have removed the uniqueness of the United Kingdom in being the only producer of postage stamps not to have its country name on its stamps in honour of its origination of the adhesive postage stamp in 1840. In 1966 Gentleman created a small single-coloured profile from a coin by Mary Gillick
. The project waited until the miniaturisation of the new definitive effigy that the Stamp Advisory Committee
(SAC) had advised the Postmaster General on 13 January 1965 be chosen, from profiles and engraved images based on a photograph.
The first essays were submitted by Andrew Restall and Arnold Machin
with Harrison and Sons
printers' assistance. They worked from photographs by Anthony Buckley, then from ones by Lord Snowdon
, the Queen's brother-in-law. Machin had just finished work on the new coin's effigy based on the photographer's pictures. The competition began with more artists officially invited during Summer 1965, but at a meeting on 26 January 1966, the SAC's members decided to let only Gentleman and Machin continue work on the design.
Arnold Machin's method was to sculpt a bas-relief in clay
and moulds, which he reworked and corrected depending on what the SAC required. The printing essays were then done by Harrisons & Sons from photographs of the sculpture, completed with the additions and adornments by designer Machin. Quickly, he decided to simplify the effigy with just the Queen wearing a tiara and the four regional flower emblems, like the Wilding series
. Yet these flowers were also dropped: Machin's design would eventually have only the Queen's profile and the value of the stamp
.
In March 1966, the Stamp Advisory Committee decided to make new photographs of the Queen available to Gentleman and Machin. They were taken by John Hedgecoe
on the following 22 June. Elizabeth II selected the pictures to be given to the artists and Gentleman continued work on the "photographic alternative" to Machin's sculpture.
During the second period of 1966, Machin replaced the tiara with the George IV State Diadem
on request of the SAC, the same diadem as was previously seen on the Penny Black
. The Queen asked for a corsage at the bottom of her sculpted neck. The final sculpture is a rectangle of plaster, 16 inches long and 14 inches wide, kept in a London-based British Postal Museum & Archive
vault.
The last adjustments to the final plaster image and to the lighting during photography created four effigies. They were unveiled to philatelists on the pre-decimal stamps, the first ones issued 5 June 1967.
Concerning the original colours, Machin encouraged the use of a clearer effigy on a single-coloured background. The 4 pence ("4d") was given a very dark brown, inspired by the Penny Black
and requested by the Queen herself. But the Post Office did not fully respect Machin's views and in the first years of the series would also issue bi-coloured stamps and clear-to-dark gradated backgrounds.
point of view, the "Machins" are far more complex than the simple design might suggest, with well over a thousand varieties of colour, value, gum, phosphor banding, etc., known. Since the first stamps were issued pre-decimalisation
, they exist in both old and new currencies. As postal rates changed, new denominations became necessary; the design has been adjusted periodically, for instance to use a gradient shade in the background; perforations have been changed; and so forth. In addition, for the regional stamps of 1971, regions' symbols designed by Jeffery Matthews
were added to the basic design.
Initially the stamps were produced by Harrison & Sons using photogravure
, with the high-value designs being larger and engraved
. Starting around 1980, The House of Questa and Waddingtons Security Print also took up Machin printing in order to keep up with demand, producing their versions via lithography
.
Apart from the many values of normal-sized stamps, there have been two different formats used for "high-value" definitives. In 1969 a larger and more square format was used to issue stamps of 2/6, 5/-, 10/- and £1 face value, and was used again in 1970 for the decimal currency values of 10p, 20p and 50p. (The £1 stamp had the lettering re-designed in 1972 and was re-issued. This version is usually seen as a 'decimal' edition as opposed to the 'pre-decimal' stamp.) In 1977 a taller portrait format was used for the large £1, £2, and £5 stamps, and also at various times between 1983 and 1987 for the odd values of £1.30, £1.33, £1.41, £1.50 and £1.60. These values were withdrawn after the introduction of the "Castles" high-value stamps
of 1988.
In 1989, as a workaround to the problem of fast-changing rates, "non-value indicator
" (NVI) Machins used textual inscriptions "1st" and "2nd" to indicate class of service rather than a numeric value. The following year saw the first commemorative adaptation of the design, with the classic William Wyon
profile of Queen Victoria
appearing behind and to the left of Elizabeth, marking 150 years of British stamps.
1993 saw the introduction of both self-adhesive
stamps and elliptical perforations on the lower vertical sides of them, the latter as a security measure.
On the high value stamps, "Iriodin" ink was used to give them a shiny appearance and ensure the difficulty of their reproduction.
In February 2009, security features were increased on "Machin" self-adhesive stamps to avoid the reuse of uncancelled used stamps retrieved on mail. Both the effigy and the background were printed with continuous "ROYAL MAIL" iridescent
printing. Two ellipsoidal shear panels were added to each stamp and the water soluble layer between the stamp and the adhesive was abandoned. These two later features were intended to render the stamps difficult to take off mail and to store for reuse (but in effect are easily overcome by the careful use of a sharp knife edge). Collectors are advised to not attempt to soak such stamps off, but to save them on pieces cut from the envelope.
The security features also included a minute change to the background printing of "ROYAL MAIL" where one letter is replaced to identify the source of the stamp. For example, instead of "ROYAL MAIL" in one place in the upper right of the stamp is printed "FOYAL MAIL" to indicated that that stamp came from a booklet of four stamps. This feature made it easier to identify the source of an individual, used stamp and track down production problems.
The initial palette of 14 colours was chosen after extensive testing. While most were solid colours, the 1/6d and 1/9d used different colours for effigy and denomination, while the 10d and 1/- had backgrounds that varied from darker on the left side to lighter on the right. The dark olive-brown shade of the 4d value, the most often-used stamp of the time, was personally selected by the Queen as being the available colour most reminiscent of the Penny Black
. However, in practice this proved difficult to distinguish from the 5d's dark blue, automated machinery could not always see the phosphor bands on the stamps, and even football pool organizers complained that it was too hard to read the date and time of cancellations. In 1969, the 4d value was changed to vermilion
, which in turn required a colour change for the 8d, which was reissued in "eggshell blue".
In preparation for decimalisation in 1971, the BPO prepared a new palette of colours, enlisting the Applied Psychology Unit of the Cambridge University to test individuals' abilities to quickly identify colours. The results pruned a selection of 25 down to the 14 used for the decimal stamps.
During the 1970s a third effigy/ background colour format emerged in addition to the existing light head-dark background and the light head-graded background; the new variation consisited of head the same colour as the background, with just the shaded detail picking out the image. (In more recent years the light head-dark background has become near universal.)
Over the years, rate changes required new denominations, and in order to make colours available, older stamps had to be withdrawn. For instance, the 11p rose of 1976 was withdrawn in 1980, and the colour reused in 1983 for a 23p stamp. A re-introduced denomination could not normally get its old colour back though; the light green 17p of 1980 was withdrawn in 1981, reissued in steel blue
in 1983, withdrawn 1986, and reappeared yet again in 1990, this time in dark blue.
In 1983, Aubrey Walker of the Royal Mail's R&D department proposed a fixed assignment of colours to rates, on the theory that the classes of service changed much less frequently than rates. This still did not solve the problem of clerks detecting usage of old stamps with lower rates - they would have had to read the denomination rather than just glance at the colour - and so a system of "light" and "dark" colours was suggested, the two variants alternating at each rate change. Artist Jeffery Matthews
was then hired to develop the actual colours, and in 1985 presented eight pairs totalling 16 colours. The colour pairing idea turned out to be unworkable, but the colours were adopted, and in 1988 Matthews developed another 15 as rates continued to be changed.
. But, the Queen herself has subsequently rejected the proposed designs.
In March 1981, after Raphael Maklouf
's effigy was chosen to appear on new issue coinage, a proposal was made to replace the Machin's effigy by 1983; in time for the 30th anniversary of the Queens's coronation. The Post Office's Ron Dearing obtained agreement from the Queen, even if she expressed through a letter by her deputy private secretary that "Her Majesty is very content with the Machin effigy and thinks that a work of real quality is required if this is to be replaced."
Under the supervision of Post Office design adviser Barry Robinson
, Jeffery Matthews
prepared alternative essays from March 1982 pictures of the Queen by Lord Snowdon
. Matthews used many different positions of the head and shoulders, from profile to full-face. Essays with the latter position were designed from the photographic representation and from a portrait drawn by his son Rory Matthews. In 1983, Robinson ordered new portraits by different artists : drawn by John Sargeant, painted by Timothy Whidborne and Brian Sanders, later engraved by Czesław Słania in 1984. Harrisons and Sons printed these essays. But, they failed to please the Stamp Advisory Committee
.
In June 1985, a new working group proposed a change to the original Machin stamp design. It comprised a bicoloured (grey effigy on a coloured background); Jeffery Matthews then worked on a different cut of the shoulders and neck, for a horizontal stamp. As Arnold Machin
must be informed on any modifications of his original design, Barry Robinson and Jeffery Matthews visited him on 23 October 1985. Machin refused any changes by anyone except himself and didn't appreciate being approached after the proposed changes were finalised.
Following the abandonment of all of the proposed changes during the 1980s, some of Jeffery Matthews's designs were later used: the horizontal format served for the first self-adhesive stamp
s in 1993 and for the "higher rate" stamps of 2006.
Another attempt to alter the design was proposed on the occasion of the 150th anniversary of the Penny Black
in 1990. The Queen's decision not to agree to any changes swiftly ended the move.
Ever changing Machins
From the initial Harrison printings through to the present there has always been a wealth of study material for the Machin collector of any level. The fact that printers and printing methods change so frequently keeps the collection of Machins alive and hugely interesting. As is usual with a new printer, such as happened when Enschede, Waddington, Questa and Walsall were engaged, subtle changes occur giving rise to new varieties.
The latest printer to be awarded considerable printing contracts for Machins is Cartor and its lithographed Machins are certainly a match for quality against the best EME issues from the likes of de la Rue and Walsall. Cartor however has given collectors a new strand of Machin types from its Prestige Booklet panes and later mini-sheets to expand collections even more.
Prestige Booklet Panes
There has been a series of Prestige Booklet Panes produced since the first "Wedgwood" prestige booklet of 16 April 1980 starting with the "Stanley Gibbons" issue of 19 May 1982, consisting of a 3-square panel of 9 stamps or 8 stamps with a central non-value label.

The wrong typeface
All printers have in recent years been given a technical brief on printing Machin stamps from Royal Mail and Cartor would have had the same brief. To reduce the risk of any mistakes the brief would set the standard for every element of the stamp including the typeface to used for the value. The standard typeface used currently throughout the Machin issue is a modern Garamond, however it would appear that Adobe has a quite different "5" character. This value made an appearance on the 5p Deep Ash Pink value of the Classic Album Covers pane of 7 January 2010, though it has since been corrected on all other printings. Quite how this came to be printed with this incorrect font has not been explained, although differences in type fonts are not new and can easily be seen on the early NVI gold issues.
Mini sheet printings
The best quality Machins are to found in the eight values of the Colour Palette mini-sheet printed in photogravure by de la Rue and the eleven stamps of the 2010 Festival of Stamps mini-sheet printed in lithography by Cartor. Both sheets were superbly printed and gave rise to all-new types and sub-types.

However, the stamps were quickly withdrawn and destroyed because the Somali clients did not appreciate them, the United Kingdom being the former colonial power in the region

Apart from the many values of normal-sized stamps, there have been two different formats used for "high-value" definitives. In 1969 a larger and more square format was used to issue stamps of 2/6, 5/-, 10/- and £1 face value, and was used again in 1970 for the decimal currency values of 10p, 20p and 50p. (The £1 stamp had the lettering re-designed in 1972 and was re-issued. This version is usually seen as a 'decimal' edition as opposed to the 'pre-decimal' stamp.) In 1977 a taller portrait format was used for the large £1, £2, and £5 stamps, and also at various times between 1983 and 1987 for the odd values of £1.30, £1.33, £1.41, £1.50 and £1.60. These values were withdrawn after the introduction of the "Castles" high-value stamps

1993 saw the introduction of both self-adhesive

stamps and elliptical perforations on the lower vertical sides of them, the latter as a security measure.
On the high value stamps, "Iriodin" ink was used to give them a shiny appearance and ensure the difficulty of their reproduction.
In February 2009, security features were increased on "Machin" self-adhesive stamps to avoid the reuse of uncancelled used stamps retrieved on mail. Both the effigy and the background were printed with continuous "ROYAL MAIL" iridescent

printing. Two ellipsoidal shear panels were added to each stamp and the water soluble layer between the stamp and the adhesive was abandoned. These two later features were intended to render the stamps difficult to take off mail and to store for reuse (but in effect are easily overcome by the careful use of a sharp knife edge). Collectors are advised to not attempt to soak such stamps off, but to save them on pieces cut from the envelope.
The security features also included a minute change to the background printing of "ROYAL MAIL" where one letter is replaced to identify the source of the stamp. For example, instead of "ROYAL MAIL" in one place in the upper right of the stamp is printed "FOYAL MAIL" to indicated that that stamp came from a booklet of four stamps. This feature made it easier to identify the source of an individual, used stamp and track down production problems.
Colours
The most striking aspect of the Machins is the rainbow of colours. Since the designs are all identical (or nearly so), it was critical that each denomination be produced in an easily-distinguished colour. Worse, the likelihood of rate changes meant that additional colours would be necessary, since old stamps were still valid and could appear on mail.The initial palette of 14 colours was chosen after extensive testing. While most were solid colours, the 1/6d and 1/9d used different colours for effigy and denomination, while the 10d and 1/- had backgrounds that varied from darker on the left side to lighter on the right. The dark olive-brown shade of the 4d value, the most often-used stamp of the time, was personally selected by the Queen as being the available colour most reminiscent of the Penny Black

. However, in practice this proved difficult to distinguish from the 5d's dark blue, automated machinery could not always see the phosphor bands on the stamps, and even football pool organizers complained that it was too hard to read the date and time of cancellations. In 1969, the 4d value was changed to vermilion
Vermilion
Vermilion is an opaque orangish red pigment, similar to scarlet. As a naturally occurring mineral pigment, it is known as cinnabar, and was in use around the world before the Common Era began. Most naturally produced vermilion comes from cinnabar mined in China, and vermilion is nowadays commonly...
, which in turn required a colour change for the 8d, which was reissued in "eggshell blue".
In preparation for decimalisation in 1971, the BPO prepared a new palette of colours, enlisting the Applied Psychology Unit of the Cambridge University to test individuals' abilities to quickly identify colours. The results pruned a selection of 25 down to the 14 used for the decimal stamps.
During the 1970s a third effigy/ background colour format emerged in addition to the existing light head-dark background and the light head-graded background; the new variation consisited of head the same colour as the background, with just the shaded detail picking out the image. (In more recent years the light head-dark background has become near universal.)
Over the years, rate changes required new denominations, and in order to make colours available, older stamps had to be withdrawn. For instance, the 11p rose of 1976 was withdrawn in 1980, and the colour reused in 1983 for a 23p stamp. A re-introduced denomination could not normally get its old colour back though; the light green 17p of 1980 was withdrawn in 1981, reissued in steel blue

in 1983, withdrawn 1986, and reappeared yet again in 1990, this time in dark blue.
In 1983, Aubrey Walker of the Royal Mail's R&D department proposed a fixed assignment of colours to rates, on the theory that the classes of service changed much less frequently than rates. This still did not solve the problem of clerks detecting usage of old stamps with lower rates - they would have had to read the denomination rather than just glance at the colour - and so a system of "light" and "dark" colours was suggested, the two variants alternating at each rate change.

was then hired to develop the actual colours, and in 1985 presented eight pairs totalling 16 colours. The colour pairing idea turned out to be unworkable, but the colours were adopted, and in 1988 Matthews developed another 15 as rates continued to be changed.

in 1990. The Queen's decision not to agree to any changes swiftly ended the move.
Ever changing Machins
From the initial Harrison printings through to the present there has always been a wealth of study material for the Machin collector of any level. The fact that printers and printing methods change so frequently keeps the collection of Machins alive and hugely interesting. As is usual with a new printer, such as happened when Enschede, Waddington, Questa and Walsall were engaged, subtle changes occur giving rise to new varieties.
The latest printer to be awarded considerable printing contracts for Machins is Cartor and its lithographed Machins are certainly a match for quality against the best EME issues from the likes of de la Rue and Walsall. Cartor however has given collectors a new strand of Machin types from its Prestige Booklet panes and later mini-sheets to expand collections even more.
Prestige Booklet Panes
There has been a series of Prestige Booklet Panes produced since the first "Wedgwood" prestige booklet of 16 April 1980 starting with the "Stanley Gibbons" issue of 19 May 1982, consisting of a 3-square panel of 9 stamps or 8 stamps with a central non-value label.

The wrong typeface
All printers have in recent years been given a technical brief on printing Machin stamps from Royal Mail and Cartor would have had the same brief. To reduce the risk of any mistakes the brief would set the standard for every element of the stamp including the typeface to used for the value. The standard typeface used currently throughout the Machin issue is a modern Garamond, however it would appear that Adobe has a quite different "5" character. This value made an appearance on the 5p Deep Ash Pink value of the Classic Album Covers pane of 7 January 2010, though it has since been corrected on all other printings. Quite how this came to be printed with this incorrect font has not been explained, although differences in type fonts are not new and can easily be seen on the early NVI gold issues.
Mini sheet printings
The best quality Machins are to found in the eight values of the Colour Palette mini-sheet printed in photogravure by de la Rue and the eleven stamps of the 2010 Festival of Stamps mini-sheet printed in lithography by Cartor. Both sheets were superbly printed and gave rise to all-new types and sub-types.
