Double Tournois - Louis XIII La Rochelle mint, 15th type

The 15th type of Louis XIII's Double Tournois series reflects the relentless rationalization of French copper coinage during the 1630s, as the royal administration pushed through successive redesigns partly to combat widespread counterfeiting and partly to assert tighter control over provincial mints. La Rochelle — the H mint mark — had only recently been restored to full royal authority following the Huguenot siege and its capitulation in 1628, and its reintegration into the minting network came with close oversight from Paris.

The Droulers typology identifies no fewer than sixteen distinct types across Louis XIII's Double Tournois production, most differing in subtle ways that occupied specialists for decades before CGKL codified the sequence.
