1994 Battle of Grunwald 20 Złotych

The 1994 20 Złotych coin from Poland features an engraving of knights charging at the Battle of Grunwald, a level of detail that required master engravers to capture the frenzy of 15th-century warfare on a mere 38.61 mm diameter.

Struck in 0.925 silver by the Warsaw Mint, it weighs 16.5 grams and was issued to mark the 610th anniversary of Poland's victory in 1410. That event, a rare triumph against the Teutonic Knights, gets rendered here with historical accuracy, from lances to armor.

Exact mintage numbers? Lost to time, probably in some bureaucratic shuffle. These coins circulated briefly before becoming keepsakes.

One dry note: It's easier to handle than an actual suit of armor.
