I just know someone is going to say this got stuck in a dryer but it appears to be raised and coming from the edge so may be a cud but I'll wait for the others to chime in.
I strongly suspect that the left side of the obverse was polished off by a buffing wheel or similar device. If so, the edge in this area should appear thinner than normal and the coin should be slightly underweight.
Would have to agree the other side of mine kinda looked off almost like a grease error. To me yours doesn't look like a cud
Wow...that's interesting. I'm no expert on errors, but if it's thicker in that area, how can it be PMD? If it were material added later, I see a very smooth transition--look at the rims. Has there ever been a broken die (cud) that was partially filled with grease? You should take an edge-on shot...
These additional photos satisfy me that the coin was altered outside the mint. There is no indication the edge is thicker on the left side. It actually seems slightly thinner to me. You also never provided a weight.
Well, I certainly defer to expert opinion--expert I am not. It was initially struck by seeing little in the way of tool marks and the gradual transition to the rim. Still hard to see what's going on from the edge view. Simple explanations are usually the most compelling.
The coin is a bit thicker then it slopes down ever so slightly at the rim. You can see a hing of letters where they should be. This was not altered after the minting process. I am just trying to get if its a greaser or cud. I am leaning more towards a greaser.
100 percent not a cud. Cuds have weakness on the corresponding spot on the reverse from lack of striking pressure where the die was broken. You're does not have this weakness, and a cud that large would be very noticable. Not sure if struck through or pmd, but not a cud.
Mike what explains the extra bulge near the rim? Someone buffed it to the point where the material was soft and extremely hot then the buffer pushed up the material then cooled off to smooth transition from Jeffersons bust?
The "extra bulge" you refer to is presumably what's left of the design rim. It's also possible that some of the metal was moved around during the alteration.
