The currency comprised various cut Spanish dollars and countermarked French colonial coins.
In 1814, sterling was established as the official currency of the island.
In 1798, eight-reales coins were holed, with the plug countermarked with a script letter "T" to make 1½ bits coins and the holed dollar issued as 11 bits pieces.
Some French colonial coins were countermarked with "TB" to produce 1½ and 2¼ pence pieces.
