1990-P Jefferson Nickel
Struck on a 3.6 Gram Copper-Nickel Planchet
Broadstruck Out of the Collar
PCGS AU 58
UNIQUE (The Only Coin In Existence)
This is a unique and spectacular major mint error. The U.S. Mint stopped producing coins for foreign countries approximately 40 years ago. This is the only known Jefferson Nickel struck on a 3.6 gram copper-nickel planchet. It has been authenticated and certified by PCGS AU 58.
The diameter of this mint error off-metal is wider than the standard diameter of 21.2mm. There is an unstruck peripheral portion of the planchet on both sides that extends beyond the lettering since it is broadstruck
. It is copper-nickel but is considerably darker and has a deep copper color rather than the normal copper-nickel Jefferson Nickel color that is 75% copper and 25% nickel composition with a weight of 5 grams.
This unique coin could have been produced in a number of ways. It could be an experimental test coin using a different sized planchet, weight and composition. It could be on a planchet intended for a token or medal. It could be on a planchet intended for striking foreign coins, even though the U.S. Mint stopped producing foreign coins approximately 40 years ago. It is also possible that this unique mint error was intentionally created by modifying a planchet and then striking it by Nickel dies.
