100 Forint Zrínyi Miklós

This piece was issued to mark the 400th anniversary of the Battle of Szigetvár, where Nikola Zrinski — the Croatian-Hungarian commander — held the fortress against Suleiman the Magnificent's Ottoman forces for over a month with fewer than 3,000 defenders. Suleiman died during the siege, though the Ottomans suppressed the news for weeks to prevent a collapse in morale. Zrinski himself was killed leading a final sortie on September 7, 1566.

The Hungarian People's Republic issuing commemoratives in gold during the mid-1960s was itself an ideological curiosity — these pieces were produced almost entirely for the hard-currency export market rather than domestic circulation.
