The 1990 Mint Set is one of very few Royal Australian Mint issues to feature all EIGHT of Australia’s circulating decimal denominations. The set includes the 1c, 2c, 5c, 10c, 20c, 50c, $1 and $2. Most crucially, the 2c, 20c, 50c and $1 were not issued for circulation and will never be found in change!
