These coins  were not minted for a use in any particular French colony, but were intended for a general use in the West Indias - particularly Martinique, Guadeloupe and Saint-Dominique (Western Hispaniola). The coins were minted in France and shipped to West Indies - the mintage of these coins was usually quite small, and these coins are generally scarce.
