Does the Mint authenticate coins?
The Mint offers to the public a service for authentication of Australian decimal coins that it has produced. Each item must be accompanied by a payment of A$200 (includes GST). Should you wish to have an item authenticated, it will be examined at the Mint using a variety of inspection methods. A decision concerning the coins authenticity will be given in the form of a letter but this will not include a grading of the coin. For further information please contact the Royal Australian Mint.
