Półgrosz koronny - Stefan Batory Olkusz mint

Batory's półgrosz was struck at Olkusz during a period when the mint there was actively competing with Poznań for royal contracts, and the town's access to Małopolska silver deposits made it a logical production center. These issues span only three years — a compressed window that reflects Batory's broader monetary rationalization, which ultimately phased out the półgrosz denomination entirely in favor of larger, more efficient silver. The Kop#486–489 sequence captures meaningful die and mintmaster variations across the run, and collectors working the series distinguish them by the mintmaster's mark rather than by year alone.
