1/2 Tanga - Miguel With countermark 'PR 809'

The 'PR 809' countermark was applied by Portuguese colonial authorities to validate older copper coinage still in circulation — a common fiscal expedient when fresh minting was delayed or disrupted by supply constraints in Goa. The underlying Miguel-era tangas were struck during the reign of Dom Miguel I, whose legitimacy was itself contested throughout his rule by liberal constitutionalist forces loyal to his niece Maria II, a dynastic conflict that directly complicated colonial administration and coinage continuity across Portuguese overseas territories.
