Concerning notes, the Currency and Bank Notes Act 1928 says If any
person prints, or stamps, or by any means impresses, on any bank note
any words, letters or figures, he shall, in respect of each offence,
be liable on summary conviction to a penalty not exceeding one pound.
The penalty was changed to Â£25 in 1977 (Criminal Law Act, s.31) and to
Â£200 in 1982 (Criminal Justice Act, s.46).
