I Need Help With This LMC.

11997755 popcorn box always cracks me up. M.D. Article does a good job of explaining this odd occupancy. (Would love to find this error coin!)

If it is dropped letters, it would be very rare, I would think.

This is a post from about a year ago or so.

This is a genuine error. It was struck through a thin, previously-struck piece of metal. That previous strike was a uniface strike. The struck, uniface piece of metal was, in turn, struck into the planchet represented by this coin. This strike generated an incuse, normally-oriented version of LIBERTY. As to the doubling that is seen on the date, this is an uncommon effect associted with such errors. I don't really know why it appears, but I have half a dozen examples.

The struck piece of metal may represent the detached bottom of a late-stage die cap. But there are other possibilities, such as a piece of "coin shrapnel" from a multi-coin pile-up.

Thank you Mr. Diamond!

I liked that term. It is very descriptive. Thanks Mike.

All learn here. My first impression was incorrect. The second set of images made me call Mike in on this one.

In studying the photos further, I'm pretty confident that the intrusive piece of struck metal was the detached bottom of a late-stage die cap.

Thanks for clarifying mike, that was my original thought, but I wasn't 100 percent positive.
