Australia 1979 20c Struck on Nepal Rupee Planchet


Click image to enlarge

At 7.5g this coin is significantly underweight for an Australian 20 cent piece (11.31g). It’s actually been struck on a wrong planchet, not just a wrong planchet but a foreign planchet. In 1979 (as per the annual report) the Royal Australian Mint struck 30 million Nepalese rupees (in the same cupro-nickel composition) and it appears a stray blank jumped ship and is living the dream of being a 20 cent instead.

This coin was a gift from a fellow error collector friend -thank you.
