5 Kronor - Gustaf VI Adolf Constitutional Reform

Struck to commemorate the constitutional reform that abolished Sweden's bicameral Riksdag in favor of a unicameral parliament, this coin marks one of the most significant structural changes to Swedish governance since the Age of Liberty. The reform, which took full effect in 1971, had been debated for decades — the 1966 issue anticipates it by five years, reflecting the political confidence that passage was effectively certain by the time the dies were cut.

The .400 silver content places it in an awkward transitional period for Swedish coinage, just before silver was dropped from circulation issues entirely after 1968.
