In 1951 the Perth and Melbourne Mints produced 29,422,000 Half Penny pieces. In the same year the Royal Mint in London produced 6,960,000 pennies. The London variety can be distinguished by a 'PL' mint-mark and the Perth Mint variety can be be distinguished by a dot mint-mark located in the same spot. The Melbourne variety is notably more scarce than the Perth variety although it is still quite affordable until around MS64.
