There were two types of silver dollars minted in 1873.
If you have the kind minted for use within the US, it will have a picture of Miss Liberty seated with her body facing rightward, but looking over her shoulder. The back of the coin has a spread-winged eagle, the words United States of America and the abbreviated denomination ONE DOL.
If you have this type, look on the back of the coin to see if there's a small mint mark letter below the eagle. It may be blank or there may be a CC.
