Question On Lamination

That can contribute to the breakdown on the surface of coins. Often it is caused by the layers of the coin being rolled out that makes the surface of the coin flattened. When they are not fluid, the straight lines of metal can breakaway from the stock material.

Usually in straight lines.

Other times there is a piece of metal that is struck onto the surface of the coin.

Although flattened during the strike, they tend to breakaway and fall off the coin later on. These can be not as straight looking, and flattened very thin.

This can happen to Zincolns when part of the plating gets struck onto the surface of a coin from another planchet or from an edge that gets chipped away and deposited in chamber before the strike. Although these are not a lamination issue, but a struck through issue. The look the same, but they really are not.
On solid planchets, they are not often designated as a struck through, but they really are.


The more separated the lamination, the more interest is shown.
