1 oz Silver Proof Platypus coin minted by the Perth Mint. 

This mammal was thought to be a hoax when it was first discovered due to it's odd looks. 

The unique coin features 2 Platypus and is in a gorgeous Proof condition with frosted details rising over mirror-like fields.

This release is limited to a maximum of just 1,000 sets and would make an excellent addition to any collection.
