Overview

The coin features a platypus on the reverse side, a unique Australian mammal. The obverse side, though not clearly visible, typically features a portrait of Queen Elizabeth II.

Historical significance

The Australian 20 cent coin was introduced on 14 February 1966 with the conversion to decimal currency. The platypus design by Stuart Devlin has been a staple on the reverse of the coin since its inception, symbolizing Australia's unique wildlife. It represents a significant shift in Australia's monetary system from pounds, shillings, and pence to a decimal system.

Estimated value

Circulated Australian 20 cent coins are generally worth their face value (20 cents AUD). Uncirculated coins or those with rare minting errors could be worth more, ranging from a few Australian dollars to potentially higher for significant errors or rare variants.

Care & preservation

To preserve the coin's condition, handle it by its edges to avoid transferring oils from your skin. Store it in a cool, dry place, ideally in a non-PVC coin holder or album. Avoid cleaning the coin, as this can devalue it.
