The Perth Mint 2013 Colored Rectangular Proof Silver Coin Set is an exceptional item. Minted from 99.9% pure proof silver, each 1 oz rectangular coin is actually legal tender of the Commonwealth nation, and carries the image of Queen Elizabeth II along with a denomination of 1 dollar.
Each coin has a different species of snake, each on a different background. The realistically colored, highly-detailed images of the four snakes are applied in a special process at the Mint, as seen in the video below.
This beautiful proof silver set was limited to only 3,000 sets worldwide, and is no longer available at the Mint. Gainesville Coins is an authorized direct distributor of Perth Mint coins. Each set comes with a certificate of authenticity and a panoramic presentation case that allows viewing of both sides of the coins.
