This is a rare silver example of the 1929 Centenary of WA medal, struck by the Perth branch of the Royal Mint, later known as the Perth Mint. Rare in any condition, the silver example is very rarely seen. The bronze version, also included, was handed out to schoolchildren. 

First iteration of the famous rampant swan and ribbon. 

Amazing original condition, can ship to USA and Canada, other countries please message me.
