Australian 1920 pennies were minted in both Melbourne and Sydney. On the reverse side underneath the word "PENNY", is a scroll. Coins minted in Melbourne will have a small dot under the scroll, coins minted in Sydney will have a small dot above the scroll. Some coins have no dot and could have been minted at either the Melbourne or Sydney Mints. The "no dots" coins are classified as rare. This means of determining the mint, only applies to 1920 pennies.
