This is a 1928-1967 Ireland 1/2 Penny Sow with Piglets Cut Coin about 7/8" shown as a Pendant. Each piece starts with an original coin or medallion and is hand pierced to remove the background and release the design of the piece. The piece is then polished to remove years of use and finally goes on to the finishing process.
