This Discovery Coin is a 1920 Buffalo Nickel struck on a full size copper planchet of the same diameter, thickness and weight of a Buffalo Nickel!! Its composition is 89% CU, 8% ZN and 3% SN. The weight is 4.96 grams which is 76.54 grains. This unique Off-Metal Buffalo Nickel is unreported in Breen, Judd and Pollock.
Buffalo Nickels struck on Cent Planchets are very scarce. Buffalo Nickels struck on Dime Planchets are extremely rare. This is the first and only reported Buffalo Nickel struck on a Full Size Copper Planchet. Type Coin Mint Errors have been undervalued for over twenty years and have just started to realize their true value.
This piece was originally in a West Coast collection of U.S. Off-Metal Mint Errors. It was sold to a well known dealer who specializes in Patterns, exotic coins and other rarities. He submitted it to NGC for authentication, and upon certification I immediately purchased it.
This discovery coin was featured in a front page Coin World article. I sold it to a collector and recently was given the opportunity to handle it once again.
