1732 Brazil John V Gold Johanna 12800 Reis gVF

The 1732 Brazil Gold Johanna (12800 Réis), minted under the reign of King John V of Portugal, stands as one of the most prestigious gold coins of the 18th century. Struck from the rich gold deposits of colonial Brazil, this coin—often referred to as a “Johanna” or “Péça”—was renowned for its impressive weight of over 28 grams and exceptional purity. Its grandeur made it a dominant force in international trade, prized by merchants and treasuries across Europe, the Americas, and beyond.

In the early days of New South Wales, where currency was scarce and barter common, the Johanna played a crucial role. It was one of the original 11 coins officially recognised in Governor Philip Gidley King’s 1800 proclamation, which sought to stabilise and standardise the colony’s economy. As such, this majestic coin forms a direct and tangible link to the foundation of Australia's monetary system and colonial heritage.
