1 Groat - Sigismund II Augustus Tykocin mint

The Tykocin mint operated for only a brief window in the 1560s, established largely because Sigismund II Augustus held Tykocin castle as a personal royal residence and used it as a convenient seat for his Lithuanian treasury operations. It was never a major production facility, and its output was dwarfed by Vilnius. Kopicki 3298 is among the scarcer attributions from this mint — survival rates are low simply because volumes were modest to begin with.
