Where is the s mint mark on silver dollar?

The mint mark location depends on which type of silver dollar. For Eisenhower dollars, it's on the obverse (heads) side, just below Ike's neck. On Peace dollars, it's on the reverse (tails) side, near the edge just above the eagle's wing. On Morgan dollars, it's on the reverse side, towards the bottom, just above the letters "do" in the Word "dollar."
