Marv65 Bedrock of the Community United States 10492 Posts	Posted 05/02/2024 1:00 pm Definition: "Lamination errors are planchet errors in which the surface of a coin cracks and flakes. It is generally believed that lamination errors are caused by contaminants in the alloy that cause the metal to separate along the horizontal plane. Lamination errors can develop before or after the strike." (taken from a random internet article) Report this Post to the Staff

Laminations are there when the copper is rolled into strips. They don't develop after the strike. They may flak off after the strike, but they were there to begin with. Report this Post to the Staff
