I found this penny in the copper bin after hearing what I thought was a Canadian cent hit the pile. After searching for and not finding the Canadian I was looking for I found that this 1972 D was the coin that I had heard. At first I thought (hoped) that it was a Canadian planchet but after looking at it closely I think that it's a lamination error that was struck after splitting. It weighs 2.4g and sounds a lot like a Canadian when bounced on the wood bench and is about .048" thick.

It doesn't look like a lamination error... it could be a split or thin planchet but the strike is usually weak on those.

I realized after I posted it and saw bman's response that I had meant to say split planchet error, which is a subset type of a lamination, no?

Can you guys see the faint signs of the metal grain where the planchet split on the reverse side? There are also striations on the obverse side that are interesting. The coin is thin and its tonal qualities are similar to a Canadian penny minted in the later days when they were doing things to make the coins use less copper by making them thinner, cutting bevels, etc. I had hoped that I stumbled on a LCM minted on a CA planchet. I don't believe that it is the case because of the grain marks that are visible.

Is this kind of error very common?
Thanks for looking...
