This is my first post! I'm new to the hobby. I have an inherited collection and have spent a fair amount of time lately grading and organizing morgans and peace dollars. I've been using a grading book to educate myself. Based on the detail on the reverse of this coin and the clarity of the lettering on the Liberty Bell, I'd go with MS-63-65.
Ouch on that bag scratch on the back left field! If it weren't for that, I'd go 65. Heck, I'll still give it a 65! Don't see FBL, though...sorry.
I got it for $7 last year and I thought it was an MS63, but I value your opinions and I'm still not sure.
You have it in-hand, now, sooo...you know how that goes. I don't think a bag mark, however nasty, would keep it from being graded by the TPGs, though.
I'd go with with AU-58-MS60. This one appears to have a few more scatches than the previous one (right side of obverse and lower left of liberty bell).
