The Perth Mint recently announced sellouts of two 1-ounce of .999 pure silver bullion coins with privy marks.
One mark depicts a monkey and appears on a special 2016 Australian Kookaburra coin and the other one shows a Bavarian Lion and is on a unique Lunar Series II 2016 Year of Monkey coin.
"Traditionally, a privy mark is a small mark of differentiation in the design of a coin added for the purpose of identifying the mint," the Perth Mint describes.
The Perth Mint introduced their first privy-marked issue in 1992 on a 2-ounce Kookaburra silver coin. Since then, it and other world mints have released many silver and even gold coins with specialized privy marks.
As for the coins that sold out, the maximum mintage for the 2016 Australian Kookaburra Silver Bullion Monkey Privy Coin was 50,000 while the 2016 Year of the Monkey Silver Bullion Lion Privy Coin was 30,000.
As bullion coins, the pair were released to the market through official distributors in Australia, Europe, North America and Hong Kong. Today, the two are available from coin and bullion dealers from about $8 to $16 over their silver values.
Below are a few more photos of the coins.
