Well that seals it for me now, not a dropped letter at all. This looks like post mint damage. Thanks for the 400x picture it really cleared it up!
Way, You asked for an opinion on CT about your quarter. I understand that you don’t like what you’re seeing in the replies. However, it is what it is. If you still want to spend money to confirm that these are just bagmarks, that’s your prerogative. You might want to read up more on how to identify error coins before continuing your pursuit. If you do, you’ll find that most mint errors are raised above the surface of the coin, not incused or ‘dented in’ to it. Good luck in your hunt.
Hey... Way don’t worry... I understand... I’ve had a few coins I thought were worth more than face value... these people really DO know what they’re talking about...
