2 Zlotys Dzieje Złotego

Part of the NBP's long-running "History of the Złoty" collector series, this issue commemorates Poland's own currency history — a subject with considerable irony given that the złoty was suppressed under communist central planning and only restored as a genuinely convertible currency after the 1990 Balcerowicz reforms. The Nordic gold alloy, a copper-aluminum-zinc-tin composition developed specifically for high-security circulation coinage, was adopted across multiple European mints in the 1990s largely for its resistance to counterfeiting and consistent striking behavior.
