There have been three sets of coins in Ireland.
 In all three, the coin showed a Celtic harp on the obverse.
 The pre-decimal coins of the Irish pound had realistic animals on the reverse; the decimal coins retained some of these but featured ornamental birds on the lower denominations; and the euro coins used the common design of the euro currencies.
 The pre-decimal and original decimal coins were of the same dimensions as the same-denomination British coins, as the Irish pound was in currency union with the British pound sterling.
 British coins were widely accepted in Ireland, and conversely to a lesser extent.
