Square pattern Penny, 1921
Type 12
Mint: Melbourne

Between 1919 and 1921 a series of experiments were undertaken for a square coinage in nickel to replace the large bronze penny and halfpenny coins. This was the design adopted for circulation but legislation was never put in place and the concept was dropped. The nickel acquired by the mint to strike the circulation coins was used in 1929 for the New Guinea penny and halfpenny coins.

Edge Description



The production of bronze penny and halfpenny coins at the Melbourne Branch of the Royal Mint began in 1919. The first order from the Commonwealth began "pending the introduction of nickel coins..." leading mint authorities to believe that the introduction of nickel coins was imminent. Between 1919 and 1921 a number of experimental square patterns were produced.
