I don't know too much about Morgan's. not sure how this would grade. I may send it to NGC or pcgs. Unless you think it's bad. I believe it is the 7 tail feather version. Thanks!
It is an 1878 7TF with Reverse of 79 Variety but due to some slight wear on the hair over Miss Liberty's ear, it might squeak by with an MS-62 Grade with mottled surfaces (irregular toning spots)! Nice coin but not really worth the value of paying to have it certified, graded and holdered!
I think the reverse would make an MS63 grade (or better) but I doubt the obverse would. Still it's hard to tell exactly from a photo. Go to a couple of coin stores and get their opinion.
You can weigh your coin against Morgan Dollar in BU condition. I notice heavy toning on your coin or maybe it’s just the way pictures are taken. You can get a great deal of information about this famed U.S. coin on this site dedicated to Morgan Silver Dollar. I think you’ll be pleased with what you learn.
