Ducat - Emery of Amboise Agnus Dei

Emery of Amboise served as Grand Master of the Hospitallers from 1503 until his death in 1512, administering the Order from Rhodes during a period of acute Ottoman pressure following Mehmed II's failed siege of 1480. These gold ducats were struck to the Venetian ducat standard, a deliberate choice that ensured acceptance in the eastern Mediterranean trade networks the Order depended upon for provisioning and mercenary payment.

The Schlumberger reference places this among a small documented group — the X designation signals an unresolved die classification, and surviving examples in any grade are infrequently encountered at auction.
