The coin certainly looks authentic and it is certainly uncirculated and can't be XF which is a circulated grade. The current greysheet value in MS64 is $52, in MS65 is $92. Btw, all of these dollars depict Liberty, this one is called a Peace Dollar. If you try to call it a Liberty Dollar, you are going to get corrected.
That's at least low-mid AU. I've come across a lot of raw silver at coin shops and few Peace Dollars looked that lustrous.
