50 Reales 'Cincuentín' - Felipe IV

The cincuentín was never intended for everyday commerce. These massive cobs — struck in Navarre under royal license rather than at a Castilian mint — functioned primarily as prestige pieces and large-value settlement instruments, circulating among merchants and treasury officials rather than passing through ordinary hands. Pamplona's output was limited, and survival rates are low relative to the Segovian machine-struck macuquinas of the same period.

Felipe IV's chronic war financing, stretched across the Thirty Years' War and the simultaneous Catalan revolt, kept the Spanish treasury under relentless pressure throughout the 1650s. The 1652 date falls just as Barcelona surrendered, ending twelve years of Catalan secession.
