I'm pretty sure it's not worn or anything. All it is, is a single dot, but it's looks to big to be a faded letter. This worth anything?
It's on the bottom right of the quarter when the letter (such as P S) would be. I'll try and get a better picture
There's a close up. Sorry of its blurry, using my phone. Then sorry for the confusion I just don't know what those marks are called
Do you have any idea how many coins are produced by one die? Any idea of how many dies are used every year? There are well into the hundreds of thousands of those out there. I don't know of anyone that collects that kind of "error". It's a spender. Live with it.
