That would be a coin of the Irish pound, which has since been replaced by the euro.
Such a coin does not exist. The Irish 10 Pence coin was first issued in 1969.
Éire is the Irish language name for Ireland, which you will see on Irish stamps and coins, so it is an Irish coin.
Ireland does not use the dollar and never has, so there is no such thing as an Irish 1 dollar coin. Ireland was using the pound in 1952, but there was no 1 pound coin. So whatever coin you have, cannot be either an Irish one dollar coin nor an Irish one pound coin from 1952.
