99.999 % of the time I agree with paddy and when I'm not sure I just pass. But, considering the Mint has never really cured it's problem with copper plating issues, anything is possible. I could go with post mint heat induced but all I can really see is some toning on this pic. I would like to hear what @Fred Weinberg or @furryfrog02 have to say about this?
That is interesting. I would also lean towards post mint altering of the plating. I'd like to see what it looks like on the edge just out of curiousity.
The planchet seems thicker on one side than the other. one reason that I thought it could be attributed to the minting process
If you have an electric stove, heat up one of the "burners" to red hot, grab a Zincoln, and start playing. You can create all sorts of neat things as long as you don't overcook them.
that would actually point to a process post mint rather than the minting process. The coins are "smashed" between two dies and if the dies are properly aligned, the resulting coin should be of uniform thickness if the planchet is complete when it enters the coining chamber. BTW- LOVE your name
I'm leaning toward PMD because I see a raised area on the reverse that corresponds with the vertical damage on the obverse. Chris (not Fred or Frog!)
I don't like my cow mooing back at me as I eat it Probably why I don't eat a lot of beef. We went to Fogo De' Chao a few years ago and almost all the meat was medium rare/rare so I didn't get to eat much.
