Does anyone know how common/rare a 1942 Irish Ha'penny is?

Answer 1

The 1942 Irish 1/2 penny KM# 10 sells for about 10 cents in low grade up to over $5.00 in mint state. It has the highest mintage of all 1/2 pennies struck from 1939-1943. Non were struck again until 1946. So it is the most common. The Irish series of coins with the animals on them, are a well collected series, even here in the States. There are lots of Irish Americans and there ancestors contributed a lot to this country.
