| Reverse description | The royal arms of Portugal in an ornate italic-style shield, surmounted by a royal crown and flanked by elaborate asymmetrical Baroque foliate and scroll ornaments. The shield displays the traditional Portuguese armorial bearings, including the five escutcheons charged with bezants and the red border with castles. The overall design reflects the high Baroque aesthetic prevalent in Portuguese colonial numismatic art of the mid-eighteenth century. The denomination 6400 Réis is implied by the coin's standard type within the series. |

| Additional information |
The 6400 réis was the largest gold denomination in colonial Brazil and the workhorse of transatlantic trade during José I's reign — these pieces moved bullion from Minas Gerais to Lisbon in quantities that made Portugal briefly the wealthiest crown in Europe. The Bahia and Rio de Janeiro mints operated under distinct administrative oversight, and the two series carry different mint marks that collectors treat as separate issues despite sharing the same royal authority.
The Marquis of Pombal's sweeping fiscal reforms after 1755 directly affected production schedules at both facilities, particularly following the Lisbon earthquake, which redirected royal attention and treasury resources for several years.
