I'm a complete novice when it comes to Goss, but i've heard of the name and when I saw a nice small trinket bowl(?) with a crest that refered to Lord Crewe Bishop of Durham i had to have it. i've seen the bowl advertised on an auction site and it said unsigned...the bowl i have is signed. is this more or less rare than an unsigned version? can anyone give me an approximate date of the item and possibly an idea of its value...thanks
