I think the OP is talking about the circle next to the star. Looks like an acidic liquid spot? John1

Hello all, this one and the Quarter I posted came out of the same unopened 1973 Proof set. Bought it since that was my birth. If it is a Acid Liquid spot, Is this something that happens often at the mint? Thank you for the help, Edward M.

That seems like a very poor example for an unopened Proof set ?

It doesn't look like a die ring. Die rings are open while this is a solid disc. I'm not sure what it is from here. Is the disc raised, incuse, or flush with the field?

Maybe some small foreign matter that got onto the die. Is it incused?

Hello all, it looks incused, but flat with the field. Thank you for the help, Edward M.

Since it's level with the field, it's not a struck-through error (unless it's a retained struck-through error). But since there's no surrounding fissure, it's most likely a stain.

I had this exact circle on a Kennedy half dollar years ago, an back then it was described to me as a metal bead rolled into the planchet material.

Hello all, it is Incused, but at the same time flat with the field. If what Atrox001 is correct what may of possibly happened. Then that would be possibly, why it is both incused and flat with field.

Hello all, but if that happened, would the Planchet stock be hot at the time the Metal Bead was rolled into it. Because, if the Stock was cool, wouldn't the bead be raised, if rolled onto it. But those are just theroies, if its possible. Also, where would this of occured, Planchet Stock Processing or during the Minting Process?

It can't be both incuse and level with the field. They are mutually exclusive conditions.

The Circle looks flat with the field but where the field and circle meet, there is a space between them. Something like, if you have ever punched leather( slight gap between leather and insde punch), unless you punch to hard and go through. But there is no sign of that on the opposite side.
