Tried my best to take pics, but can try again with a better camera if it seems worth it. I can't find much info on US State Quarter errors as there seem to be relatively few. Major defining characteristics are: 1) Much thicker than regular quarter 2) Slightly smaller diameter 3) Reeded edge only about 5% present and not at all in most places 4) Much deeper lip on reverse 5) edge does not seem to be perpendicular to the faces of the coin - it's noticeably trapezoidal when looking on it edge wise - with the acute angled wider diameter side being the obverse and the obtuse angles smaller diameter being the reverse. You should be able to readily see all of these in the cell phone camera images and they are much more apparent in person. Obverse seems pretty standard and don't see much in the way of doubling or anything else indicating it was struck more than once. I'm not very familiar at all with errors, can anyone tell me if this is worth investigating further? Thanks!
Someone tried to make it into a ring like cpm9ball said which can be referred to as spooned. Not worth anything over 25 cents. Still always neat to find about tho!
I agree....it does look like the beginnings of a ring...they are started by hammering on the edges as evenly as possible...
My advice is to stick around the forums and you'll see this exact type of damage with some regularity.
