Struck to celebrate the 40th anniversary of Australia’s iconic dodecagonal fifty cent, this 2009 Gold Proof is a tribute to a landmark in decimal coinage. Introduced in 1969, the twelve-sided 50c became recognisable, pairing practicality with bold national symbolism.

Featuring Queen Elizabeth II on the obverse and the Commonwealth Coat of Arms on the reverse, this .9999 fine gold issue weighs 33.63g.

With a limited mintage of just 800, it remains a scarce modern classic.
