| 表面の説明 | Crowned royal arms of Castile and León displayed centrally within the field, showing the quartered shield with castles and lions in their respective quarters. The arms are surmounted by a crown, with partial legend running around the periphery. As characteristic of macuquina (cob) coinage, the flan is irregular and the design is only partially visible, with much of the surrounding legend and date lost to the clipping and striking process. |

These are cob coinage — macuquinas — struck by hammer between crude dies on irregular planchets, the product of a mint system optimized for speed and bullion throughput rather than precision. Mexico City was the dominant silver mint in the Spanish empire during this period, feeding an Atlantic trade network that stretched from Seville to Manila.
Felipe IV's reign saw the 1642 debasement scandal at the Mexico City mint, in which assayers were found to be systematically underweighting and debasing cob silver — a fraud that implicated officials at the highest level and resulted in executions. Coins struck in those years are now catalogued separately by specialists, as the actual fineness often fell well below the stated .931.
