Commentary on Sections Section 1: Amendment of Coinage Act 1971
9.The effect of the changes made by section 1 to sections 1(6) and 3(1)(cd) of the 1971 Act is that the variation from the standard weight of any coin struck by the Royal Mint (not just gold coins of a denomination mentioned in Schedule 1 to the 1971 Act) shall be measured in accordance with provision made by proclamation. Under section 3 of the 1971 Act, Her Majesty has the power, exercisable by proclamation, to determine various attributes of coins struck by the Royal Mint, including permitted variations from standard weights. This allows, for example, a weight of sample in excess of one kilogram to be specified in the proclamation relating to the one kilogram coins.
