Description

The threepence (3d) (Irish: leath reul) coin was a subdivision of the pre-decimal Irish pound, worth  1⁄80 of a pound or  1⁄4 of a shilling. The Irish name (leath reul) literally meant "half reul", the reul being a sixpence coin worth the same as the Spanish real (a quarter of a peseta). As with all other Irish coins, it resembled its British counterpart, as the Irish pound was pegged to the British pound until 1979.

The coin was minted at the Royal Mint starting from 1928, and ceased to be legal tender after decimalisation on 31 December 1971. Ireland did not adopt the brass, dodecagonal three pence coin that Britain used between 1937 and 1971.
