I see corrosion but it still looks like a Rpm south east . I don't think it 's a plating problen but i;m not that famlier with it. I have to say the second images looks pretty good to me , but lets see what the others have to say. Fankie Boy
The corrosion builds up under the surface of the top layer. It will give the effect of an extra letter being there, but it is not present. If he was to take more pics of the area at different angles, then I suspect he would see this. It would probably flake off at the opening. If you want good examples of RPM's for this year here are a couple from coppercoins.com.....http://coppercoins.com/diesearch.php Jessie edited oops, just go to their website to find out, I gave the wrong link.
Hi, It is indeed a "spot o' rot" It is really more circular than like a letter D. The unfortunate thing is that a circle looks like the right side of a D. There is rot at the center of the opening of the anomaly you are pointing out. Thanks, Bill
