King George II of Great Britain died in October of 1760. In that year, small denomination copper coins were scarce in Ireland. None had been minted for several years. To meet the demand, farthings and halfpence were privately minted in Dublin. A button-maker named "Roche" on South King Street is traditionally thought to be the designer and minter. The coppers circulated extensively in Ireland. Many were brought over to America where they joined the hodge-podge of copper coins already in circulation. Although, not specifically minted for the colonies, several examples have turned up in archaeological digs in areas such as Maryland and New York.

The obverse of the farthing and the halfpenny shows a generic male bust wearing a laurel wreath with the motto "VOCE POPULI" (By the Voice of the People). The reverse depicts the seated figure of Hibernia with a harp and the legend "Hibernia" above and the date 1760 below.

Some of the varieties suggest that another mint or, perhaps a contemporary counterfeiter, may have produced additional coins.
