Disclaimer: This is just a guide to give you an idea of what your coin might grade. Often coins will grade higher on one side vs. the other. In example, it's possible for a coin to grade G4 on its obverse, but grade VG8 on its reverse. Also, this guide is not a claim that one's coin will obtain any grade listed if submitted to a third party grading service.
Draped Bust coin types have two different reverses. The Draped Bust Half Dollars had a "Small Eagle" reverse from 1796-97 then it was changed to the "Heraldic Eagle" or Eagle and Shield reverse. Each have their own grading characteristics and both are sample in the images below, so keep that in mind when grading Draped Bust Half Dollars.
