What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
One major variety is the 1800 "Dotted Date" Draped Bust Silver Dollar. This coin features a die defect on the obverse of the coin around the 1800 date. This resulted in a number of dots and blobs within and around the first "0" in the 1800 date. An example closeup image of the dotted date is depicted below:
