So I'm fairly new to coin collecting and don't have much experience with error coins. From what I see this coin has got to be an error. It's certainly not hard to see what I'm referring to. My thing is I just don't know if this is considered a error or not. Would really appreciate any helpful feedback. I have uploaded pictures and circled in red the area I'm referring to. The "4" in the date is almost none existent like it was only partially stamped on the planchet. Then there is the mint mark which looks to be more then one letter on top of each other.
Also if this is a error would anyone perhaps know what it might be worth. The condition is also flawless. It looks like it's never even been used once. Well thanks for any help.
