⅙ Thaler - Frederick II

Frederick II's monetary reforms of the early 1750s were driven less by economic principle than by wartime necessity. The Seven Years' War was approaching, and Frederick needed a debased silver coinage that could fund military operations without exhausting the treasury. The 1750 Graumannsches Münzsystem, which this piece predates by two years, set the stage — but coins struck in 1752 already reflected the deliberate reduction in fineness that would define Prussian emergency-era silver.

The Olding FR#63 reference places this among the earliest emissions of the type before subsequent debasements made even .521 fine look respectable by comparison.
