1/2 Escudo - João V Lisboa, Bahia, Rio and Minas mints

João V's gold coinage reform of 1722 standardized fractional escudo production across multiple colonial and metropolitan mints simultaneously — an administrative ambition rarely attempted in Portuguese monetary history. The Bahia and Rio mints in particular were operating under constant logistical strain, dependent on freshly refined Brazilian gold that moved through the interior in mule trains before reaching the coastal houses.

The proliferation of Gomes reference numbers across this single type reflects genuine mint-by-mint die variation, not cataloging conservatism. Collectors working this series differentiate pieces primarily by mintmark punching depth and letter style rather than gross design differences.
