Collector Basics: Unplated planchets
- Published: Dec 8, 2014, 12 PM
Editor's note: This is one in a series of Coin World Collector Basics posts on numerous types of planchet errors.
New in U.S. coinage, unplated planchets became possible in 1982 with the introduction of the copper-plated zinc cent (and briefly in 1943 with the zinc-coated steel cents).
The zinc-copper alloy planchets are plated after they are punched from the strip but some planchets miss the plating process. Coins struck on the unplated planchets are grayish-white in color.
Beware of cents which have had their plating removed after leaving the Mint. Although beyond the ability of a novice collector to detect, any of the authentication services currently operating should be able to distinguish between a genuine piece and an altered version.
