This Is A 2003 D South Dakota State Quarter. Appears To Have Metal Missing

I would have included the reverse but it's difficult to download on an Android. You said if there is a flat spot that means what exactly? Because I did notice what you said was opposite

There is really no sense in making things this difficult to respond or upload. But I'm in the process of uploadig reverse

Who wants to be a member of something they can't use because it's made so difficult and floats around like a rubber ducky in the ocean when trying to post

Thank you sir

This is the reverse of the 2013 State Quarter

That's your final answer?

Learning errors is hard, but the key is knowing the minting process and being able to match what you think is an error to something that happens there. There's an endless number of ways a coin can be damaged that we'll never be able to identify. That's why you have to look at it as 'How could this happen at the mint?'

There are some great articles on the website to explain it. Look at the sticky at the top of this forum.
