| Additional information |
In 1854, Portuguese colonial authorities applied a small crown countermark to circulating copper in São Tomé and Príncipe as a revalidation measure — a common administrative response to chronic coin shortages in Atlantic island territories where metropolitan supply was erratic and local populations routinely used whatever coinage came to hand. The host coins were typically earlier Portuguese provincial issues, countermarked to authorize continued circulation at a fixed value rather than withdraw and replace them.
The Gomes P5.14 reference places this among a documented series of crown punches, distinguishable by punch diameter and placement from later revalidation campaigns on the same islands.
