Everything but the lams looks like damage to me.

 Just a lamination issue, not a struck through

None-the-less, nice example of a lamination issue.

If it is not a struck through, what are all the raised pieces of copper debris?

Strike-throughs are incuse, not raised. I agree that it's just a lamination. Still a cool coin!

Has anyone looked at the link. From what Coop said, to my understanding, it is struck through and still attached. Please read the other thread. I don't know, I am confused now. Thank you.

The 1945 in the other thread has small pieces of debris struck into the metal. Notice that they're flush with the surface and are not linear. The lamination on your coin is linear and exists within the coin, not just on the surface. The date is a little harder to tell- I can see how that could be debris, but it seems more likely to me that it's part of the same lamination. The raised bits also seem to be lamination peels; struck-in debris should just fall out rather than fold. I don't know, I could be wrong.

Still, what about the missing elements in line with the lamination. Some seem too deep or does lamination peel that way? Or is it also a bad alloy mix? This is just a quandary for me based on what I have learned thus far. I wish I had the coin made right after this one. Or just before. Thank you all for your input.

Quote: Some seem too deep or does lamination peel that way? Or is it also a bad alloy mix? This is just a quandary for me I agree with the majority. It is a delamination (separation linear of the material). The delamination occur in 80% of the time on the begin of the planchet roll. If the delamination it is very thinly can glue on the roll and then will be a inclusion in the planchet given the effect which it is LAMINATION (union of two parts by pression, heat, glue, etc). The alloy in this case is out of the equation, we can forgot this idea, and I will not discuss here this. You say missing parts, and probably you confound with the cracking planchet. No, this happened at the end of the roll of the planchet and is really uniform because it is a complete structural separation of the crystals. The missing parts is normal in the cases of delam because the force applied on the strike will make this thin delam to crack. You do not must be perplex (quandary).

So all the little pieces around the date are part of the lamination issue and not struck through into the metal? http://goccf.com/t/397906

But they struck troughs peel off, they leave leave an incuse mark, just like lamination peel will leave an incuse mark. Not sure which direction the peel is coming off, but through the center is definite. Lamination errors can can peel on one one area of the coin or others. Note this example:  The left side peel off first, the center was assisted to come off and the right side, is still in tact. This coin sold for 5 figures. Why? Got me. I guess I found the right buyer.
