Decimalisation of the currency was discussed during the 1960s. When the British government decided to decimalise its currency the Irish government followed suit. The legislative basis for decimalisation in the Republic was the Decimal Currency Act, 1969. The number of pence in the Irish pound was redefined from 240 to 100, with the penny symbol changing from "d" to "p". The pound itself was not revalued by this act and therefore pound banknotes were unaffected, although the 10 shilling note was replaced by the 50p coin. New coins were issued of the same dimensions and materials as the corresponding new British coins. The Decimal Currency Act, 1970 made additional provisions for the changeover not related with the issue of coins.
