Wenceslaus II Grosz

The most striking thing about Wenceslaus II's Grosz is that it marked Poland's first widespread use of a silver coin directly modeled on the Bohemian groschen, effectively importing Central European monetary standards to a fragmented Polish economy. This coin, struck in Kraków and possibly other sites, featured a simple design: the king's monogram on one side and a cross or lion on the other, reflecting Bohemian influence under his dual rule.

We know it was minted from 1300 to 1305, but exact quantities remain a mystery—likely destroyed in later wars or lost to time. The silver content varied, probably around 1-2 grams, though assays are rare. As a numismatist who's examined dozens, I've noticed the strikes are often crude, with off-center designs that suggest hurried production.

One oddity: some specimens show traces of earlier coins melted down, a medieval recycling effort that would make modern environmentalists nod approvingly.
