1919 AUSTRALIAN PENNY UPSET DIE ROTATION ERROR see for info https://www.pcgs.com/news/enigmatic-australia-1919-and-1920-dot-penny-coins This is quite a rare coin in this condition. GRADE IS UNC/GEM For the Australia Penny coinage, the die production occurred at the Royal Mint in London. The hubs were kept there and never shipped to mints in Australia for the coinage of 1919 or 1920. Instead, completed dies were shipped to the Melbourne Mint from both the London and Bombay Mints. The first penny coinage from Australia in 1919 featured dies with no dots, struck at the Melbourne Mint with dies from London. According to Mark Duff, an authority on the coinage of Australia, the Melbourne Mint exhausted the supply of working dies and was forced to create a new master die pair from the working dies in order to continue production. The Melbourne Mint added a dot under the bottom scroll as an unofficial mintmark for the Melbourne Mint. To mark this event, proof coins featuring this bottom dot variety were minted. The Sydney Mint, which was gearing up for production of penny coinage, was sent dies from the Melbourne Mint with the date 1919 featuring dots above and below the scrolls to mark the production of such coins. Hence, the three varieties for 1919 are No Dots, Dot Below (Melbourne Mint), and Dots Above and Below (Sydney Mint).
