The Bahamian dollar (B$) is the official currency of The Islands of the Bahamas which is on par with the US dollar. Both currencies can be used interchangeably throughout the islands.
History
The Bahamas orginal used the British Pound before 1966 when it was replaced with the Bahamas Dollar at a rate of 1 Dollar = 7 Shillings. This rate allowed the establishment of parity with the U.S dollar, due to the Sterling/Dollar rate then being fixed at £1 = $2.80. This has often been used to explain why the Bahamas have a 15 cents coin, since this was roughly equivalent to 1 Shilling.
