Now, you're drawing a conclusion from a formulated supposition that the Mint would polish out a mintmark and use the coins for its Mint Set? If that were the case, we should expect to see hundreds, maybe thousands, of Mint Sets with the same anomaly. No way, Jose! Chris
That's not an omm. An Over Mint Mark would be a d over an S or vice versa. An RPM is a D/D or an S/S. What you have in neither. Just a D mint Washington quarter.
Now, see! All you can do is run away when you don't have a good response. Ask anyone, here! The cello provides no protection at all. If you want to get serious, this wouldn't be considered an OMM anyway! Chris
I stand corrected. Not a OMM. I had to leave for awhile, never ran away. So Chris time for you to walk away and learn to be more polite. Best photo I can take with a camera phone. I have to run another errand, so I am going to run away. For awhile.
Chris is plenty polite, but what most don't understand is that he knows what he is talking about. The thing is you took it personal. We are here to help if someone needs but we also have zero responsibility to answer, let alone argue with someone over an answer given.
Chris said it is a fluke. I say it is a mis-placed mint mark. It can be seen better in person with a loop or a microscope. Anyway I'm happy with my find.
The thing is there is nothing there but a single D mint mark. You can think that but I challenge you to actually learn how coins are made and how they age. It's your coin you can call it what ever you want but don't be surprised when experienced folks don't see it the same.
