some sort of as-made fluke or PMD?

Trying to envision what this is all about. What is the wisdom of these boards of what is going on by MM?

Wild guess.......small cud.

It’s cud-dling the MM.

Would like to see, or know what the
edge of the coin looks like where the
'cud' thing is -

What is the date of the coin, please?

There appears to be rim damage to
the right of that area, under 'ENTS'.

Could be a retained cud, but I don't
recall seeing this one before -

More likely a damaged fold-over from
the rim, or possibly a defective planchet
and a 'pinched' fold over rim burr-like area.

Edge photo and date, please

It looks shiny in the MM area where it looks folded over I wonder if it’s post mint damaged

Hemispherical

I’m always in learning mode and “fold-over” has me into learning overdrive.

it is a 16-D, which was plagued with all manner of die state and strike problems. Coin is not in hand so I can't provide a rim image. I will say that the rest of the piece appears earlier die state and decently struck

Interesting .... more pictures... edge and full coin.. would be helpful. Cheers, RickO

IMHO it is a rim break. Note how the "line" (inside and next to the rim) continues through the curve below the mintmark.

Could be solder remnant if it was ever made into a charm. That would be the top of the obverse so the placement is slightly suspect.

I’m with Fred. Planchet problem.
