Denier - Bolesław I the Brave

Bolesław I of Poland seized Bohemia in 1003 after backing a dynastic coup against the Přemyslids, holding it for roughly a year before being expelled by Henry II of Germany. These deniers are the physical record of that occupation — one of the few Polish rulers ever to strike coins in Bohemia under his own authority. The tenure was too brief and the political situation too unstable for extensive minting, which explains the extreme rarity of Cach#226 survivors.
