On the back, look to the left of the eagles wing.
If the coin has a mintmark, it's on the reverse above the letters DO in dollar.
Nowhere, because there's no such thing. There were no silver dollars minted in the US that year.
No US 1799 coin will have a mintmark, all were struck in Philadelphia.
In 1907 there were no mintmarks on pennies.
A 1901-S Silver Dollar - aka - Morgan Dollar - is worth in a mint state of AU50: $225.00.
You've got to give us the mintmark and the exact year. Morgan dollars have a mintmark (if any) above the D and O in dollar on the reverse.
You need to give us a date and mintmark (if the coin has a mintmark) for us to help you. A "liberty head dollar" can refer to nearly any silver dollar minted before the Eisenhower series started in 1971 and coins have very different values depending on the condition, mintmark and year.
Please post new question with a date, the US Mint has never used a "E" mintmark.
