Three main types exist:

Early types (621-718): the middle section of Kai (開) does not touch the top of the hole.
Middle types (718-732): the middle section of Kai does touch the top of the hole, and the two horizontal strokes of Bao (寶) do not touch the vertical lines.
Late type (732-907): the middle section of Kai does touch the top of the hole, and the two horizontal strokes of Bao usually touch the vertical lines (and these examples are typically cruder).

Hundreds of reverse varieties exist, including various position of lines, dots, and crescents. Hartill gives the following reverse varieties (indicated by letters), with each letter variety being applicable to each Hartill number:
