John1 Moderator United States 56855 Posts	Posted 09/21/2015 10:50 am A few questions. How should I label this? Any collector interest? Value if any? Thanks all,John1 Report this Post to the Staff

Pete41 Valued Member United States 261 Posts	Posted 09/21/2015 11:40 am Interesting lamination? I see there are a slew of other vertical lines on the coin in front of and into the bust. Some must collect these but no idea on value. It would go into the oddities stash for me. Report this Post to the Staff

durkastani Valued Member United States 452 Posts	Posted 09/21/2015 12:07 pm Looks like lamination to me as well. It doesn't spark my collectors interest. Report this Post to the Staff
stoneman227 Pillar of the Community United States 2376 Posts	Posted 09/21/2015 12:31 pm Looks like the plating split along a linear plating bubble. Split plating. Report this Post to the Staff
Pete2226 Pillar of the Community United States 3331 Posts	Posted 09/21/2015 12:33 pm This is a copper plated cent - the plating is 8 microns thick. I am not certain that it is able to sustain a lamination peel. I did not know the zinc alloy contained any kind of lamination. Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 09/21/2015 1:09 pm Several times I have seen people say that a zinc cent can't have a lamination. Why not? What causes a lamination? A gas bubble or foreing inclusion in the ingot that gets rolled out to create the strip. Frequently it is because of problems in the alloy mix but there is no reason why a bubble can't happen in a pure metal strip, especially one with a low melting or boiling point such as zinc. Get the melt a little too hot and gas bubbles can form in the melt from vaporized zinc. Yes this could just be a split plating bubble, but it does look like it has a good chance of being an actual lamination. Report this Post to the Staff
stoneman227 Pillar of the Community United States 2376 Posts	Posted 09/21/2015 2:02 pm I'm sure you could truly say a plating bubble is actuallya spot where the plating has delaminated from the core since the plating and the core are different layers of the coin. If the bubble were large enough it would be very much like a "traditional" lam Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/21/2015 2:27 pm What does the reverse look like and the edge in that area. A closer shot might be helpful. You might also check to see if under a raised area if there is copper plating? If so it may have been struck through a piece of copper foil that came off another cent? If so you might see there is folds over the edge at the ends of the raised area. Report this Post to the Staff
Pete2226 Pillar of the Community United States 3331 Posts	Posted 09/21/2015 5:00 pm I think it is *really* very interesting! I would like to own it! I don't know that I would want to pay very much, though! Report this Post to the Staff
