The Irish Free State, subsequently known as Ireland, resolved in the mid-1920s to design its own coins and banknotes. Upon issuing the new currency, the Free State government pegged its value to the pound sterling. The Currency Act, 1927 was passed as a basis for creating banknotes and the "Saorstát pound" (later the "Irish pound") as the "standard unit of value." The legal tender notes issued under this act began circulating on 10 September 1928.
