@Rick Stachowski I'm having trouble trying to understand how a raised rim around a hole could be anything other than PMD. Even if was a strike through, how would the edges be raised? The striking pressure would keep the field flat. The metal is obviously malleable, so that rules out stress induced brittleness. Maybe of an object was pressed into the planchet and did not deform during striking and was subsequently pulled out leaving a raised rim, but I really think that is pretty unlikely. Hope I've explained why I think it's PMD
Here's a strike-through, that ken potter wrote some articles on . http://www.numismaticnews.net/article/black-eyed-grant-cause-explained http://www.numismaticnews.net/article/black-eyed-grant
Looks like copper plating blisters in the NT of Cent area, but I can't tell what's between the ONE/CENT. Looks like a lamination, if it were copper. Because it's zinc, I don't know. I've not seen a plating blister that shape and smoothness on the sides - so no idea, based on what I am able to see.
Rich, I don't think more photos will help...me, at least. If you attend the FUN show, or the ANA, I'd be glad to view it in-hand. It's an anomaly, but I can't determine exactly what.
Damn. I just can't compete with you members. With my eyes i see a lot now but when in hand i don't have what it takes. You members are great teachers when i couldn't see this stuff on the sunniest day. I can see it now. Thanks. What I'm saying. I just cant see this stuff unless you members share your greatness in finding. Forever gratfull for your pics
I feel the exact same way. @Rick Stachowski shows me something and half the time I have to look up the reference to see it. Learned a lot from this thread.
