1973-D -Large Raised Area. Die Dent Maybe?

It is remnants of a clash, Sudz. Good eye. Bob gave the answer on another forum. He said, "It appears to be a clash remnant Jay. Looks like it was a pretty hard hit and has since been abraded and has worn down a bit." It looked so "tall" and wide, I didn't even think about a clash.

Thanks coop. I am now not sure what it is.

This is Mike Diamond's assessment:
Mike Diamond said, "These have always been a mystery to me. They occur on many 1973-D cents, and in association with more than one die pair. I don't think they're clash marks as they're always ill-defined and always appear in the same area. No other "clash marks" are seen on either face. In severely affected specimens the Memorial columns can be waisted and damage occurs in areas well-removed from the main defect."

I'm gonna try to find the other one I threw in my copper bin a week or two ago. I think it is in better condition.
