1 Dollar Sierra Leone Company, type '100'

The Sierra Leone Company was a British abolitionist venture chartered in 1792 to govern the Province of Freedom settlement at Freetown, but this dollar was struck in 1791 — the year before the charter — when the enterprise was still operating under its predecessor, the St. George's Bay Company. The coins were intended to provide a stable local currency for a colony populated largely by Black Loyalists evacuated from Nova Scotia and liberated Africans, a population for whom British coinage was both scarce and practically useless in daily trade.

The KM#6 designation covers what is effectively a pattern-adjacent issue; surviving examples are rare in any condition, and the .902 fineness closely mirrors contemporary Spanish milled dollar standards — almost certainly deliberate, to encourage acceptance alongside the pieces of eight already circulating on the West African coast.
