Crooked as an eleven dollar bill

hello
what is the origin of this term /where dose it come from( As crooked as an eleven dollar bill)

It is one of several sayings used to describe someone or something that is dishonest/suspicious. As there is no such thing as a legal $11 note (bill) it must be a fake. In the UK a similar phrase uses the denomination '9 Bob note' (9 shillings - an obsolete currency unit, but there was never any such note.)
