| Reverse description | A fully rendered armillary sphere occupies the central field, its bands and meridians finely engraved in a grid-like pattern with a diagonal sash bearing the crowned royal cypher 'J' (for João) across its equator. A small crowned cartouche appears at the base of the sphere. The circular peripheral legend PECUNIA.TOTUM.CIRCUMIT.ORBEM ('Money encircles the whole world') runs along the outer margin in raised Latin letters, separated by dot stops. The armillary sphere is the traditional Portuguese imperial device, long employed on colonial coinage. |

| Additional information |
São Tomé and Príncipe received its own dedicated copper coinage during the João period not out of colonial generosity but chronic shortage — the islands had no functioning mint, and the Rio de Janeiro facility struck these pieces while João himself was still in Brazil, having fled Lisbon ahead of Napoleon's 1807 invasion. The Portuguese court-in-exile remained in Rio until 1821, and the colonial minting apparatus followed accordingly.
Gomes lists multiple subvarieties under JR.01, distinguished primarily by die alignment and punch characteristics from the Rio facility.
