The acetone bath may have harmed the "blending" of the clad & copper from 10:00 to George's nose. Note how the rest of the missing area has a ragged edge. ~ Chris
Here you go @Danomite. Not sure if these help. Chris- I understand your point. The coins blending area and ragged edge you're talking about didn't change after the acetone. The coin looked this way before the acetone. It just took the dirt and scum off the coin.
Yes it does, thanks for the pics. I'm leaning towards environmental damage. The edge as @cpm9ball mentioned looks out of place. The rest of the pattern could be explained by wicking effect of some sort of chemical. Maybe a cupholder coin? I'm not an error expert by any means, die varieties are my thing
IMO, it looks like a chemical stain. I would not expect to see a color gradient since the clad outer layer and copper core are discreet layers. And since the are discreet layers, I would also expect to see some sort of margin where the layers meet. I don't feel that the striking pressure is enough for that remnant to be completely removed. Just my opinion
Missing clad layer would be the entire clad layer on one side. What you meant was Partial clad layer. But I also dont think yours is a mint error. Here are examples of partial clad or defective clad layer missing from my collection
Yes looks like staining. If you weigh it and it comes in at 5.67 you know it's not missing even a partial clad. Always weigh a coin first that you have an idea about.
