Australia 2007 Sydney Harbour Bridge Dollar Cmm PCGS MS63 Double Mintmark Error


Accidently Mintmarked Twice

Accidently Mintmarked Twice

This commemorative dollar struck for the 75th anniversary of the Sydney Harbour Bridge in 2007 has a C mintmark. Well it actually has two C mintmarks after being accidently given a second mintmark in the steel on the bridge.

It’s most probable that this happened on the mobile coin press at the Canberra coin fair in February 2007.
