Collectable 20 Cent Coins of Australia

Celebrate the intricate design history of Australian decimal currency with our premium selection of collectable 20 cent coins. While Stuart Devlin’s iconic platypus design has been a staple of Australian pockets since 1966, the 20c denomination has also hosted some of the Royal Australian Mint’s (RAM) most memorable, low-mintage commemorative milestones.

At FORTYMILLION, we specialise in securing mint-fresh, collector-grade examples of these versatile coins. From highly sought-after historic commemoratives—such as the 2001 Centenary of Federation state series, the 1995 United Nations issue, and popular military tributes—to pristine specimens found within official RAM proof and uncirculated year sets, our inventory is curated for the discerning numismatist. Avoid the scuffs of everyday change and secure investment-grade pieces that boast sharp details and full mint lustre.

Official Government Mintage: Every coin is a genuine, legal-tender issue struck by the Royal Australian Mint.
Collector-Grade Preservation: We source choice uncirculated, specimen, and proof condition coins, carefully housed in archival-safe capsules or cardboard holders or saflips.
