Obol - Matthias Corvinus

Matthias Corvinus spent much of his reign financing an exceptionally expensive professional army — the Black Army — through aggressive fiscal measures including repeated currency debasements. The obols of his middle period reflect this pressure: silver content declined incrementally across issues, and the ÉH#578 type sits within a sequence of reductions that numismatists can track through die study and metal analysis rather than any official announcement from the royal mint at Buda.
