Kazimierz III Wielki — Casimir the Great — remains the only Polish king to earn the epithet in the nation's history, and his reign from 1333 to 1370 left an administrative and legal architecture that outlasted the Piast dynasty itself. He codified Polish law in the Statutes of Wiślica and Piotrków around 1347, effectively unifying a kingdom that had spent decades fragmented under competing claimants. He also founded Kraków Academy in 1364 — later Jagiellonian University — making it one of the oldest universities in Central Europe.
The 62.2g fine gold specification places this squarely in the one-troy-ounce collector format that NBP has used for its premium historical series. Four-nines purity is the relevant technical distinction here, as earlier NBP gold issues were struck in .900.
