1915 Lincoln Cent
Struck on Full-Size Nickel Planchet
(75/25 Cu-Ni)
One of Two Known

This is the second known authenticated and certified Lincoln Cent off-metal prior to 1916. The discovery coin was recently featured in a front page Coin World article and described as a possible Mint Experiment Test Piece. This coin was also struck on a full-size planchet of Nickel composition but was graded higher at AU 55.

Below is the listing for the discovery coin.

Pollock lists as #2028, "Nickel. Plain edge. Unique? Listed in Judd as being a Mint Error."

S&N Labs analyzed this off-metal for elemental composition using scanning electron microscopy with energy-dispersive x-ray spectrometry (SEM-EDX). The composition was a copper-nickel alloy.

This is the same alloy that was used to strike the Buffalo Nickels during this time period. To view a unique 1920 Buffalo Nickel struck on a full-size copper planchet, authenticated and certified by NGC, click here.

This 1915 Lincoln Cent is on a full-size planchet as the rims are full and sharp. If it was struck on a foreign planchet, there would be weakness in the rims.
