| 表面の説明 | The host coin is a Spanish colonial cob-style 8 Reales struck in the macuquina (hammered) tradition, displaying the quartered royal arms of Castile and León at centre — alternating castles and lions — flanked by the pillars of Hercules with the denomination mark VIII visible in the upper field. The irregular, cob-cut flan exhibits typical characteristics of colonial cob coinage with a partially visible encircling legend in the field. The coin shows considerable wear and a prominent crack through the lower portion of the flan, consistent with the rough handling common to circulating macuquina issues. |

In 1663, the Portuguese Crown ordered circulating Spanish 8 reales — the dominant trade coin of the Atlantic world — to be countermarked and revalued for use in Brazil. The operation was a fiscal measure: by stamping foreign silver with royal authority, Lisbon could absorb Spanish coin into the colonial monetary system without minting from scratch. João IV had died in 1656, so the countermark bearing his name was applied posthumously under his successor Afonso VI, an administrative anomaly that has puzzled catalogers for generations.
The host coin beneath the countermark is almost always a cob-style cob (macuquina) from one of the South American Spanish mints — Potosí being the most frequent source.
