6400 Réis - Pedro I

Brazil's first emperor authorized this denomination almost immediately after independence was declared in September 1822, with the Casa da Moeda do Rio de Janeiro retooling production to strike a distinctly Brazilian gold coinage rather than continuing the colonial Portuguese padrão. The 6400 réis was the highest gold denomination in circulation and saw genuine transactional use among merchants and landowners — not merely ceremonial production.

Pedro I abdicated in 1831, ending the series abruptly. Examples struck in the final years of his reign, particularly 1829 and 1830, carry notably lower mintage figures than the earlier dates.
