Instructions
See if your coin is dated from 1840 to 1873 and features Lady Liberty seated and with her head turned around to the right. If so, you have a Seated Liberty Dollar.
Determine if your coin was minted from 1873 to 1885 and features Lady Liberty seated to the side with her arm outstretched. If so, you have a Trade Dollar. The words "Trade Dollar" appear on the reverse.
Look to see if your coin contains the year 1878 to 1904, or 1921, and it features a side view of a curly-haired Lady Liberty's head. If so, you have a Morgan Dollar.
Examine your coin to see if the year is from 1921 to 1935 and features a side view of Lady Liberty's head on the obverse and an eagle peacefully perched on the reverse. If that is the case, you have a Peace Dollar.
