| 裏面の説明 | Central cross pattée dominates the field, dividing it into four quadrants. The upper left quadrant displays the crowned royal monogram 'F' (for Fernando/Ferdinand VI), while the remaining quadrants bear partial heraldic devices. The mint mark 'P' for Potosí and the assayer's initial appear to the left of the cross, with the denomination numeral 'I' (one Real) visible above. The date and assayer letters are partially legible within the surrounding legend, consistent with the irregular fabric of hammered cob coinage. A post-mint hole is present in the lower central area of the field. |

Ferdinand VI never visited the Americas, but the Potosí mint — operating at over 13,000 feet in the Bolivian altiplano — was among the most productive silver operations in the world during his reign, fed directly by the Cerro Rico deposits that had been hemorrhaging metal into the Atlantic economy since the 1540s. The cob-style macuquina coinage produced here was notoriously irregular, and colonial minting scandals at Potosí were nothing new: the fraud uncovered in the 1640s under assayer Francisco Ramírez had shaken the entire Spanish monetary system decades earlier.
KM#37 spans the full thirteen years of Ferdinand's reign, meaning die wear and assayer variations are the primary tools for narrowing a specific piece's date of production.
