obvspacerev

One of only two known foreign coins
struck on a U.S. Wartime Nickel Planchet!

indentThis is a new discovery and is unique. Just authenticated and certified by NGC, this Australia Florin was struck at the San Francisco Mint on a U.S. Silver Wartime Nickel Planchet.

indentAustralia Florins were struck at the San Francisco Mint from 1938 to 1945. The composition is .925 silver with a weight of 11.31g, a diameter of 28.5mm, and a thickness of 2.3mm. These coins have a small "S" mint mark for San Francisco below the Australian Coat of Arms.

indentU.S. Wartime Nickels were struck in San Francisco from 1942 to 1945, during World War II. The composition is 35% Silver, 56% Copper and 9% Manganese. The weight is 5g with a diameter of 21.2mm.

indentWartime Mint Errors from 1942-1945 are among the most coveted and sought after by mint error collectors. Obviously the most famous are the 1943 copper Lincoln Cents that sell for $300,000 and the 1944 steel Lincoln Cents that sell for $50,000 to $100,000. Even a 1943 Lincoln cent struck on a Curacao 25 Centstukken planchet sold in a Heritage auction for $31,200.

indentThere are only a handful of world coins struck on U.S. planchets known during this wartime period. This amazing new discovery is the first Australian coin struck on a U.S. Silver Wartime Nickel planchet, and only the second known foreign coin struck on a U.S. Silver Wartime Nickel planchet. The only other one known is a 1942 Bolivia 50 Centavos struck on a U.S. Wartime Nickel Planchet that was struck at the Philadelphia Mint. This historic off-metal belongs in a collection of unique Australian coins, U.S. wartime coinage, or unique mint errors.


A regular Australia Florin has a diameter of 28.5mm.
