Frankfurt's 1649 output coincides directly with the Peace of Westphalia celebrations — the city served as a principal venue for Imperial Diet assemblies and had a vested civic interest in commemorating the treaty's conclusion after thirty years of war. Pattern strikes in gold from Frankfurt's mint during this period were almost never intended for circulation; they were presentation pieces, distributed to dignitaries or retained as proofs of the die-cutter's work.
JuF 461b is the gold variant of a type struck in base metal for actual use. At 1.7 g, the planchet sits at roughly half the weight of a standard gold gulden, suggesting the gold was sized to match the silver Albus's dimensions rather than any gold denomination's intrinsic value.
