Gold Ecu with sun of Brittany - Louis XII

Louis XII inherited Brittany's incorporation into the French crown through his marriage to Anne of Brittany in 1499 — a union that was itself politically coerced, Anne having been forced to dissolve her prior marriage to Maximilian I. The sun mintmark on this écu is not decorative but administrative, denoting the Rennes mint and reflecting the duchy's retention of its own minting apparatus even after political absorption.

The .963 fineness held firm throughout this type's production run, a deliberate policy of monetary stability that distinguished Louis XII's reign from the debasement cycles of his predecessors.
