This is a very nice 1913S Variety 1 Buffalo Nickel, but it does have some wear on the hair ribbon, on the high spots, a few nicks on the rim and the luster is a little off. A strong EF or may be a AU 50, but not a MS.
The grade in this case would be limited by the amount of remaining luster - based on the pic I'd say VF35 - XF40.
