The stamp series

First series

The first twelve stamps, the low-values up to 1 shilling, were issued during 1922–23 whilst the three high-values, 2/6, 5/- and 10/- did not appear until 8 September 1937. They were printed by typography

In 1944 the 1/2d and 1s issues were replaced by the corresponding values of the set printed to commemorate the tercentenary of the death of Michael O' Cleirigh.

Gerl designs

Watermarked paper

Known after its German designer, Heinrich Gerl who won the 1966 international design competition, this was the first new design of Irish definitives in 31 years for the high-values and 46 years for the low-values. Sixteen stamps debuted between 1968–1969 on four release dates. The graphics were all based on early Irish art motifs: a dog was used in one colour for the low-values, the elk
Irish Elk
The Irish Elk or Giant Deer , was a species of Megaloceros and one of the largest deer that ever lived. Its range extended across Eurasia, from Ireland to east of Lake Baikal, during the Late Pleistocene. The latest known remains of the species have been carbon dated to about 7,700 years ago...

 designs were on the high-values.

These stamps used the letter 'p' (Irish pingin) to denote pence rather than the 'd' (Latin denarius) used in the UK, so the three pence stamp bore '3p'. These stamps can be distinguished from the next issue by the presence of the letter 'p' after the numeral.

Decimal currency

With the introduction of decimal currency on 15 February 1971 the Gerl designs were reused in different colours and values and released between 1971 and 1974. A total of 18 single value stamps appeared plus three different multi-value coils; one 5p value and two different 10p se-tenant

 strips.

Since the previous series had used the letter p to denote pre-decimal pence, the stamps in this series just used a numeral to denote the denomination, so, a three-pence stamp bore the digit 3 with no 'p' after it.

Unwatermarked paper

The last of the Gerl definitives consisted of 14 dog designs, 9 elk designs and 6 winged ox and eagle designs issued on 17 different dates between 1974 and 1980. For the first time a £1 value was put on sale. Some of the values produced were to replace different values as needed because of changing postal rates due to inflation.

Dual currency

On 11 June 2001, six values in dual currency (Irish & euro) appeared using birds from the previous Irish currency issue. Both Irish pound and euro values were printed on each stamp and in most cases this required the designs to be reset in a smaller form to accommodate the additional currency text.

Until 1956 most booklets had half of the front cover devoted to advertising, and until 1963 booklets also had serial numbers on the front cover: two numbers indicated the year of issue and serial number (in that order on the early issues but with the order reversed for later issues), until 1963 when the serial numbers ceased.
Since 1983, most booklets are no longer stitched; the stamp pane, or panes, are glued into a folded card cover.

Until 1988, when the Dublin Millennium booklet containing commemorative stamps was issued, all booklets contained only definitive stamps. Since then, An Post has issued both commemorative and definitive booklets, with three times as many commemorative booklets issued. In 1990 An Post issued the first booklet mixing definitive and commemorative stamps in one booklet and also on a single pane.

Many booklet stamps can be identified by one non-perforated edge, though a few are perforated on all edges. On booklets up to 1977, the printing plate construction enabled both upright and inverted watermarks in equal quantities owning to a gutter dividing rows 6 and 7 in the sheets of 12 x 10 stamps. The gutter was used for stitching during assembly, requiring rows 4–6 and 10–12 to be turned through 180 degrees so those panes could be stitched on the left of the booklet.
