An image of the opposite side would be helpful. It pushed outwards, then it is coin damage.

Im wondering if maybe it has something to do with not having been annealed properly, making it brittle when the die struck it?

Or, maybe the planchet was already a problem planchet and the metals weren't mixed properly to begin with? I have no idea. I'm just making things up in my head that sound plausible at this point.

@element47, I will take a stab at it for you. I am seeing PMD. Looking at the reverse you see deeper gouge marks staring closer to the center of the coin, moving outward and slightly to the right. Since the depth of the gouges are deeper towards the middle of the coin, and external forces are greater at initial impact, add the fact the missing portion has a cleaner and thinner break away towards the rim, that would be the direction of travel of the tool or object causing the damage. Also, the striations or gouges appear deeper on the right side vs the left, which is probably why you only see one small bounce impact towards the rim and favoring the right side. Had this been a planchet issue, you would still see the rotunda in full detail. IMHO, All that said, it is just a SWAG on my part. |

 How deep is the hit on the dome? Pressed inwards, level with the fields? Taking another look, it looks like that area is pushed out a bit. So that is PSD. A took a hit in the dome. Edited by coop

Well thats unfortunate. Ive not seen a coin with a hit like that yet. Ill probably keep it just for reference though. Thanks for your answers!

Well I could decide on the affected area, until I noticed on the overlay, what area could be affected. An then I spotted where it could fall. Overlays are not just for die clashes anymore.

Thats so true. I actually have a whole bunch of your overlays, and other images saved to my desktop that I use for reference. I typically use them to see what clashes might be found where. But for sure they can be used in other situations, such as this. I feel like Ive used them for other things a time or two, but I cant think of them now haha

Looks like it could be a lamination error. Hopefully Mike Diamond can chime in.

A lamination does cause the opposite side of the coin to push out. The weight is probably normal as the metal is just moved, not removed from the coin.

I think it would qualify as a planchet flaw around the dome top if it missing a chunk, but if it's not deep it could just be lamination error.
The O may have taken a hit, but guessing that's what it is.

Its about as deep recessed as the dome would be in relief. Its hard to show in pictures.The weight is 4.708 grams. So its definitely is missing a decent chunk of metal. Jeffersons bust isn't really pushed out. There is just some light toning or discoloration that kind of makes it appear that way in the photo.
So are we going with defective planchet?

Have you tried soaking in acetone to see if any of the darker material will come off?
