Hi there,

Just a new collector, inherited a chest of coins from my dad.

Looking at an error on a 41' Cent, just wondering what it is the proper name for this type of error so I can correctly write it down on the front of the coin flip I inserted the coin into; thanks for assistance.

J.R.

Looks like lamination peel.

I agree ..lamination peel (the planchet is breaking down/separating, usually due to incomplete alloy mix)

Now I am confused. 1941 1 cent coins were not a laminated type coin. Alloy: 95.5% copper, 3% tin and 1.5% zinc.

It doesn't have to be a laminated coin to have lamination peel.
To expand on what Bill in Burl stated-
Presence of contaminants in the alloy caused by improper mixing
in some instances can cause flakes of metal to break of off the
face of the coin. There are many early Canadian Coins that have
lamination peel.

As Coinguy said, "lamination peel" is just the NAME for that type of error ... it doesn't mean that the coin is laminated. It only means that the anomaly appears to look like a lamination that has peeled. As I stated before, the error is caused by improper mixing or some type of impurity that enters into the alloy during the making of the small ingots that are fed into the rolling mills. It could be oil from machinery, metal filings, or just dirt that gets rolled into the sheets from which the coin planchets are cut. They are found in nearly every denomination from any number of Mints around the world.
