I have many, many vintage Irish coins of various denominations.  If you want more or less than 12 of the 2 pence coins, I have them.  Four of the coins are dated 1971,1 is dated 1979, 6 are dated 1982, and 1 is dated 1982.  One side of each coin has a Gaelic harp and the other side a bird from a 9th century Bible. They can be easily polished to a beautiful bronze color.
