Obol - Béla IV

Béla IV's reign was defined almost entirely by the Mongol invasion of 1241–42, which devastated Hungary so thoroughly that contemporaries estimated half the kingdom's population died. The rebuilding effort that followed — new stone fortifications, resettled populations, rechartered towns — required administrative infrastructure, and coinage was part of that reconstruction. These tiny obols circulated in a country that had to be substantially rebuilt from scratch.

At 0.22g, striking consistency was nearly impossible to maintain, and known examples vary considerably in flan quality.
