Well, the provided context is about as helpful as a screen door on a submarine, so I'll have to dig into my own reserves. Answering "who is on the US silver dollar" is a bit like asking "which actor played Batman"—it depends entirely on which one you're holding!
For the classic, old-timey silver dollars that gunslingers slapped on saloon bars, you're looking at Lady Liberty. She's the star of both the Dollar (1878-1921) and the Peace Dollar (1921-1935). She gets a different profile and hairstyle on each, proving that even an abstract concept of freedom needs to update her look every few decades.
Then, things got a little more presidential. The only president to grace a circulating dollar that actually contained silver was Dwight D. Eisenhower. The "Ike" dollars, minted from 1971 to 1978, had special 40% silver collector's editions, putting a real person on the silver dollar for a change.
So, the short and sweet of it is that for most of history, it was the allegorical and ever-stylish Lady Liberty. But for a brief, shining moment in the 70s, it was good old Ike.
