An Australian 1930 Penny is the rarest coin that has ever been released into general circulation in Australian history. Only 3,000 were minted and of those, 1,500 still exist and are trading in todays market. They are still arguing about why the 1930 Penny was released at all. There are only 6 proof coins known to exist, 3 in museums and 3 in private collections. Depending on who you choose to believe, a proof 1930 Penny might go for anything between $250,000 and $500,000 AUD. One of the private collectors has recently declined an offer of $1,000,000 AUD for his proof coin. An uncirculated 1930 penny in absolute mint condition could fetch up to $150,000 AUD. If it is in less than mint condition, it might fetch as little as $10,000 to $15,000 AUD. A reputable coin dealer will be able to give a more accurate valuation. Authentication and verification of such coins is vital. The Australian 1930 Penny has recently been described as the "Holy Grail" of the coin collecting world.
