The Irish 'Barnyard Series' of coins features animals that were very important to Ireland's mainly agricultural economy.
The half-penny features a sow and her piglets. When this coin was issued, most families in rural Ireland kept at least one pig that was fed kitchen refuse and other vegetable and animal scraps. This design appeared on the first coinage of the Irish Free State in 1928 (KM2), and was carried over with a modified obverse on this issue from 1939 to 1967.
