The good news is that you paid AU & not full MS-64 price for it & it's also a key-date coin w/ a little over 4m minted.
Does the seller accept returns? IMO, even if I had to eat shipping/handling (chalk it up to a learning expense) I'd send it back & then focus on purchasing a better 1911 S.
First of all, we all started off w/ limited knowledge of numismatics. For me, it took time to learn & after 6 years, I'm still being educated daily. That being said, how much did you pay? Does the seller allow returns?
For our inexperienced members, we generally ask them to show us pics prior to purchasing, that way we can give you our honest opinions. IMO, it's a fun/interesting hobby that will last a lifetime, don't throw in the towel just yet.
