1 Bit

The "bit" denomination has West Indian roots stretching back to the Spanish colonial period, when fractional Spanish silver — particularly the one-real piece — circulated so widely across the Caribbean that local economies priced goods in "bits" long after Spanish coinage ceased to dominate. Barbados adopted the term formally, though the island's own silver coinage was always a minor supplement to a monetary system that ran largely on foreign coin and, later, British sterling.

The .903 fineness matches the old Spanish colonial standard, almost certainly not by accident.
