Oklahoma State Quarter Error, Please Help

Initially it appears to be post mint damage, can get closer and bigger images?

Someone has put a round object, such as a washer, onto the coin and squeezed it in a vice or whacked it with a hammer. There are genuine errors like this (called 'Strike-Through' errors,) but they would not leave a mark on the other side of the coin. :)

thank you john, yea I stumbled across this site trying to find info on this quarter that came out of a bankroll, but by the replies from some members in here I'm starting to think I came to the wrong forum, but some members do have pretty wild imaginations lol.....
oddcoins, I like how you come up with that scenario all from just a picture, I believe your putting too much thought into it, but if I ever need a sherlock homes, dont worry, I wont call ya !

I believe it may be the other way around and you are putting too much thought into it. We see a number of pictures of items posted almost daily from people who thought they have found a legitimate error. Once you've seen enough of the same thing, it's easy to recognize what's going on, even with small pictures. As it was posted, there are a number of ways post mint damage can occur to a coin but there is a limited number of ways a genuine error can occur. Once you understand the process in which a coin is minted it becomes easier to differentiate the legitimate from the PMD. With the coin pictured, I tend to agree with oddcoins, his scenario may not have been exactly how it occurred but he's on the right track of reasoning.

chico,

The only error here is with your comments and your post. You come for help then criticize my fellow members and friends. Nobody took the time to point out your spelling errors or your lack of proper sentence structure. This is because the members here don't pick on people. They only want to help. You may not agree with some of the comments but if you had stuck around longer you would have received more responses about your damaged coin. Alienating people here is no way to get assistance now or in the future.
