I can respect that Coop. You both always have my highest respect. I agree with your opinions 100 percent when they are based on known facts. I can't help but disagree sometimes when they are based on a theory. Theories and opinions go hand in hand. This is the place for opinions, I know because CCF thanks me for my participation every time I sign on. lol
Seriously though, when you post a picture that say's "planchet roller marks" I think it should say "possible planchet roller marks". Also, the article you posted is outdated as to Mike's suspected cause of the suspected roller marks. Here's an excerpt from his and my conversation.

Quote:
I now suspect that brown and gray-colored stripies found in nickels and clad coins are the result of both rolling and improper annealing. I suspect that the elevated temperatures of the annealing oven somehow bring out the striped pattern that is already latent in the surface metal. This conjecture would explain the greater-than-random association of stripes with discoloration and the uniform discoloration of the coins' edges.

I don't mean to go against the grain, it's just that I disagree with the theory. You both have my highest regards. This is the last I have to say on the matter.

Coop,I never gave this link because when it was made I knew considerably less about our hobby than the little I know now, and it makes me look like an idiot. I also didn't post it because I don't like helping to promote things I don't believe in. I saw your question coming, (asking for the link) that's why I said, "This is the last I have to say on the matter." I was off the hook, but after further consideration, I owe you and many of the other readers better than that. There is a lot of good information in it. Here you go.

I hope you will also amend the "planchet roller marks" in the pictures you make as that is incorrect too. You and Mike are the experts, so I think "probable roller marks" or "thought to be roller marks" or something like that would be correct. Thanks, Jim

It might be a good idea to lock the old post? The one I just provided a link for.

Oops. Sorry, I goofed. Now I know why you wanted me to email the link.
