The dollar or peso sign ($) is a symbol primarily used to indicate the various peso and dollar units of currency around the world.

The sign is first attested in British, American, Canadian, Mexican and other Spanish American business correspondence in the 1770s, referring to the Spanish American peso, also known as "Spanish dollar" or "piece of eight" in British North America, which provided the model for the currency that the United States later adopted in 1785 and the larger coins of the new Spanish American republics, such as the Mexican peso and the Peruvian eight-real and Bolivian eight-sol coins.

The best documented explanation reveals that the sign evolved out of the Spanish and Spanish American scribal abbreviation "p^s" for pesos. A study of late eighteenth- and early nineteenth-century manuscripts shows that the s gradually came to be written over the p developing a close equivalent to the "$" mark.

There are a number of other theories about the origin of the symbol, some with a measure of academic acceptance, others the symbolic equivalent of false etymologies.
