1957 Y. (p) Penny 1d Graded MS64RB by PCGS
The Australian penny was introduced in 1911 and used prior to decimalisation in 1966 with one Australian penny worth 1⁄12 Australian shilling, 1⁄24 Australian florin, 1⁄60 Australian crown, and 1⁄240 Australian pound. The coin was equivalent in its dimensions and value to the British pre-decimal penny, as the two currencies were originally fixed at par.
The obverse of the coin featured the reigning Australian monarch. Three were featured: George V, George VI and Elizabeth II. All of the pennies bearing George VI and Elizabeth II had a kangaroo on the reverse. The kangaroo image was on the Australian half penny and has since been included on the dollar coin and the bullion silver kangaroo.
During the George VI era, coins minted at Perth had a dot either at the end of the word "PENNY", after the word "AUSTRALIA" or in between the "K" and "G" above the end of the kangaroo's tail, while coins from Melbourne did not have a dot. An "I" under the bust of George VI denoted being minted in India and is only found on pennies and half pennies dated 1942 and 1943. A "PL" mintmark after "PENNY" denoted minting in London, England and is only found on the 1951 dated penny and half penny. This continued through the end of the coin's lifetime.
