Question

Answer 1

Yikes. No two errors are identical, so this would be a long list, indeed.
Misprints: One or more printings missing or inverted. Missing seals / serial numbers, blank backs, offsets (Mirror image of the front of the note appearing on the back), misaligned printings, double printings, mismatched serial numbers
Cutting errors: off center cuttings, extra paper
