The Perth Mint, which was originally founded as a branch of the Royal Mint in London, began this bullion coin series in 2010. The mint is known to issue these silver coins in two ways per year: proof coins and uncirculated coins. These coins have an amazing value, unlike other silver bullion coins, because of the small mintage of these coins. The low-mintage is paired with being part of a well-known and long-standing collection of silver coins. This is therefore one of the few precious metal coins bought for its rareness and collectability, as well as the silver bullion weight it holds.
