1 Macuta - Maria II Countermark CROWNED SHIELD over '1/2 Macuta, Maria I and Pedro III'

In 1837, Portuguese colonial administrators in Angola conducted a systematic revaluation of existing copper coinage by countermarking earlier Maria I and Pedro III half-macuta pieces to circulate at double their original face value. The crowned shield punch effectively doubled the currency supply without the expense of a new mint run — a fiscal shortcut common to cash-strapped colonial economies. Maria II, then navigating the turbulent aftermath of the Liberal Wars that had only recently ended her uncle Miguel's usurpation, had little administrative bandwidth to spare for a proper Angola recoinage.

The KM#50.2 designation distinguishes countermark placement variants, as the punch was applied by hand and its position relative to the host coin's devices varies considerably.
