Frederick II authorized this fractional thaler denomination early in his reign as part of a broader recoinage driven less by monetary idealism than by fiscal pressure from the War of Austrian Succession. The .521 fineness is notably debased relative to earlier Prussian silver issues — a deliberate policy under the direction of the mint master Graumann, who was simultaneously developing the Prussian monetary reform that would eventually standardize the Reichsthaler.
The two-year production window of 1750–1751 was short enough that surviving examples in any condition are genuinely scarce. Graumann's full reform took effect in 1750, making this type transitional by definition.
