1983-D new RPM

Now I'm not even sure if this is even a RPM or not. I looked at all the sites and to no avail could anything remotely close be found. How could this have happened?

In my opinion, it looks like part of the mintmark may be sunk into the coin. It almost looks like zinc rot. It looks like it's falling apart from inside the coin.

It doesn't appear to be a lamination issue, since the center of the mintmark appears to be sunken in below the copper plating.

Zinc rot huh I'm going to do some reading up on that one. It sounds rather harsh! Thanks Gary

I agree with Gary 100%.

That piece that is next to the D IS NOT a die chip then correct it's been lifted upward because CO2 got under the zinc coating then and that's the culprit?

Sometimes it's difficult to look at a photo like this and dissect it with precision. If we had the coin in hand and some one used a high power microscope they would have a better chance at potentially understanding what is going on.

Sure, it could be a a fragment that was lifted up. If that coin was in circulation like that for some time, additional damage could occur at a different time changing the original "look" of the coin.
