Overview

The reverse side features a swimming platypus surrounded by water ripples with the numeral '20' above it. The obverse side (not pictured) features the portrait of Queen Elizabeth II.

Historical significance

Introduced in 1966 as part of Australia's transition to decimal currency, replacing the florin. The platypus design by Stuart Devlin has remained the standard reverse for this denomination for over 50 years.

Estimated value

$0.20 AUD (Face value). Most circulated versions are worth their face value unless they are specific rare mint years or error coins.

Care & preservation

Avoid cleaning or polishing the coin as this can reduce its numismatic value. Store in a cool, dry place inside a non-PVC coin flip or holder to prevent oxidation and environmental damage.
