I can see a bit on the T in Liberty, and on the back of her neck. The picture is a touch fuzzy to really make out anything further.
Die doubling on 1922 Peace dollars is not going to be visible from those pictures. Best bet is to look at the designer's initials TRVST, and the 22, but be careful not to mistake strike doubling with die doubling. (This coin seems familiar.)
Looks like a B2 reverse, but it's tough to tell from the pictures where the obverse doubling is occurring...maybe in "Trust"? The back of the neck isn't doubling - I see a ridge behind the neck on a lot of peace dollars - that's just how many of them are struck. Like Messydesk mentioned, look at the "In God We Trust", designer initials and the date, but also take a very close look at the tiara and front of Liberty's forehead/nose. I believe there's a popular 1922 VAM w/ doubling in the tiara.
