80 Reis - João VI Bahia mint

João VI issued this copper coinage for Brazil while still ruling from Rio de Janeiro, having fled Lisbon with the entire Portuguese court in 1807 ahead of Napoleon's invasion. The Bahia mint had a complicated history of striking emergency and provincial issues, and copper denominations of this period were chronically short-supplied relative to demand in the northeastern captaincies. Hoarding of silver made low-denomination copper the workhorse of everyday commerce in Bahia's busy port economy.

The Gomes suffix variant digit in the reference number distinguishes die pairs within this type — worth confirming against plate coins before attribution is finalized.
