http://en.wikipedia.org/wiki/Dollar_sign
The sign is attested in business correspondence between British North America and Mexico in the 1770s, as referring to the Spanish-Mexican peso.[1] known as "Spanish dollar" or "pieces of eight" in British North America where it was adopted as U.S. currency in 1785, together with the term "dollar" and the $ sign.
The origin of the "$" sign has been variously accounted for. Perhaps the most widely accepted explanation is that it is the result of the evolution of the Spanish-Mexican "P's" for pesos or Spanish dollar. This theory, derived from a study of old manuscripts, explains that the "S," gradually came to be written over the "P," developing a close equivalent to the "$" mark.
Это знак песо, знак денежной единицы вообще, но не знак американского доллара! Более того, он появился еще до появления доллара!
