1769 Brazil Joseph I Gold Half Johanna 6400 Reis EF

Struck in 1769 under the reign of King Joseph I of Portugal, the Brazilian Gold Half Johanna (6400 Réis) is a stunning example of colonial-era wealth and power. Minted in Brazil from rich Minas Gerais gold, these coins circulated widely across the Portuguese Empire and were prized for their high gold content and impressive size.

Known as a “Half Johanna” or “Meia Peça,” it represents half the value of the massive 12800 Réis “Johanna.” These coins often made their way into international trade and were occasionally found in early Australian colonies during the proclamation period, highlighting their global economic reach.

Importantly, the Half Johanna was one of the original 11 coins officially valued by Governor Philip Gidley King in his historic 1800 proclamation, making it a foundational coin in Australia's early currency system.
