sovereign bolivar. The bol??var is the official currency of Venezuela. Named after the hero of South American independence Sim??n Bol??var, it was introduced by President Antonio Guzm??n Blanco via the monetary reform of 1879, before which the venezolano was circulating. Due to its decades-long reliance on silver and gold standards, and then on a peg to the United States dollar, it was long considered among the most stable currencies.
