1740-D 1/2 Sou Marque

Coin Details

Description

The 1740 1/2 Sou Marque is a French colonial billon coin worth 12 deniers, half the value of the standard Sou Marque. It was struck at the Lyon mint (mint mark D) under the authority of Louis XV, the Well-Beloved (r. 1715-1774). This smaller denomination served the same colonial territories as the full Sou Marque, providing lower-value coinage for everyday transactions in New France, Louisiana, and the French West Indies. The design follows the same general pattern as the full Sou Marque, with a crowned double-L monogram on the obverse representing Louis XV and a crowned trio of fleurs-de-lis on the reverse. The "Marque" designation identified the coin as colonial issue rather than metropolitan French currency. However, the smaller planchet means that the design elements are rendered in slightly reduced scale, and surviving examples often show less complete strikes due to the smaller striking area. Struck in billon, the 1/2 Sou Marque measured approximately 19 to 20mm in diameter and weighed between 1.0 and 1.3 grams. Being smaller and lighter than the full Sou Marque, these coins were more prone to loss and wear, which makes well-preserved survivors comparatively scarce. The billon composition, with its modest silver content mixed with copper, gave these coins enough perceived value to serve as effective small change in colonial commerce. The 1/2 Sou Marque occupied the lowest tier of French colonial silver-alloy coinage. Below this denomination, colonial commerce relied on copper or base metal pieces, Spanish fractional coins, and various informal media of exchange. The chronic shortage of small-denomination coins in the colonies made even these modest billon pieces important to daily economic life.
