1 Gross - Ludwig

Ludwig II inherited the Bohemian crown at age ten in 1516, and his reign over the kingdom — cut short at Mohács in 1526, where he drowned fleeing the Ottoman rout of his army — lasted precisely a decade. The gross issued under his name was part of a broader Jagiellonian monetary framework that struggled to maintain silver content against the pressures of cheaper Central European mining outputs flooding the market.

The .400 fineness reflects a genuine debasement relative to earlier Bohemian groschen, not a minting anomaly.
