The Royal Australian Mint has released an interesting collection of miniature money. The set includes the 1c, 2c, 5c, 10c, 20c, 50c, $1, and $2 coins in the same tiny size, stuck in 99.99% gold to proof quality.
The coins have a diameter of 11.15 mm and a weight of 0.5 grams each, which makes the coins “some of the smallest coins ever made” at the RAM. The mintage is limited to 2,000 pieces and the eight coins are presented in a wooden case with each coin individually removable.
The price for each set is AUD$536.36 for international orders and the product page can be found here.
The 4 grams of total gold content included in the set converts to 0.1286 troy ounces. As is usually the case with very small sized gold coins, the pricing is high when compared to intrinsic value. However, the pricing is consistent with half gram sized gold coins offered by other world mints. For example, the Perth Mint offers the half gram “Mini Roo” which carries a bullion finish and is priced at AUS $54.09, and the Royal Canadian Mint has a half gram Gold Cougar with a proof finish priced at $79.95 CAD.
The Royal Australian Mint has previously released a 2012 Silver Year Set with the designs of the circulating coins struck in 99.9% silver. The diameters of the six coins ( no 1c or 2c) are the same as used for the circulating versions, rather than reducing the coins to a single size. The mintage for this set is limited to 5,000 pieces with a price of $277.27.
