| Obverse description | Central field displays the large denomination numeral '40' flanked on each side by a small cross ornament, with the date '1820' inscribed below. A royal crown surmounts the numeral at the top of the inner field. The design is enclosed within a beaded inner circle, outside of which the circular Latin legend reads 'JOANNES.VI.D.G.PORT.BRAS.ET.ALG.REX', identifying João VI as King of Portugal, Brazil and the Algarves by the Grace of God. The coin's outer rim is defined by a fine reeded border. |

| Additional information |
João VI issued this copper coinage from Rio de Janeiro while ruling as king of a Portuguese empire that had, uniquely, relocated its entire court to Brazil following Napoleon's 1807 invasion of the Iberian Peninsula. The Rio mint had been hastily reactivated in 1808 specifically to serve a transplanted monarchy — a situation without precedent in European colonial history. By 1820, the year of this strike, liberal revolution in Porto was already forcing João's hand; he would sail back to Lisbon the following year, leaving his son Pedro behind.
