Missing Clad Layer Error Coins
Modern dimes, quarters, and halves are copper-nickel clad over a copper core. When an outer layer fails to bond and falls away, the exposed copper core creates a 'missing clad layer' error that is underweight and coppery.

Frequently asked questions
What is a missing clad layer coin?
It is a modern clad coin (dime, quarter, or half) that lost one of its outer copper-nickel layers during manufacture, exposing the coppery inner core. The coin looks copper-colored on that side and weighs less than normal.
How much is a missing clad layer quarter worth?
A quarter missing a full clad layer is typically worth $25–$150 depending on grade and how much layer is missing. Larger coins and dramatic examples bring more. Weigh and photograph yours in Coin AI to assess it.
