Trachy - John III Doukas-Vatatzes

John III ruled the Nicaean Empire from 1221 to 1254, and his reign was one of deliberate reconstruction — fiscally, militarily, and administratively — following the Latin sack of Constantinople in 1204. He pursued a conscious policy of economic self-sufficiency, reportedly encouraging local agricultural production to reduce dependence on foreign trade, an unusual priority for a medieval emperor. His coinage reflects a treasury trying to project imperial legitimacy from exile in Anatolia.

Billon trachea of this type are notoriously irregular in fabric, a consequence of provincial minting infrastructure that never matched the Constantinople workshops displaced by the Latin occupation.
