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.
The coin is just a dollar spend it.

If this question is about the coin's value, it's worth one dollar.
A US "penny" is actually a 1 cent coin, worth 1/100 of a dollar. A British penny (the coin's official name) is worth 1/100 of a pound sterling.
