Groschen - Frederick III-V Graz

Frederick III spent much of the 1460s locked out of his own Vienna residence by rebellious Austrian estates, at one point besieged in the Hofburg for months before Hungarian forces under Matthias Corvinus eventually drove off the rebels. His Graz mint became critical during these years precisely because Graz remained under his control when Vienna did not. The groschen issues from this period were not administrative routine — they were the coinage of a ruler managing a fractured territory from a fallback capital.

CNA 12 places this among a tightly sequenced group of Frederick's Graz groschen that numismatists use to trace output shifts during the Habsburg-Hungarian conflicts of the 1470s.
