Angola 1923-KN 50 centavos
This specimen was lot 187 in Ponterio sale 182 (New York, January 2014), where it sold for $411.25. The catalog description noted, "ANGOLA. 50 Centavos, 1923-KN. This is the only Portuguese colonial coin bearing a foreign mintmark. Very interesting and VERY RARE. Lightly toned. PCGS MS-64 Secure Holder." This type was struck 1922-23 for the Portuguese colony of Angola on the west coast of Africa south of the Congo. It was accompanied by a copper-nickel ten centavos (KM 63). This mintmarked issue may have been unauthorized as it is today very rare. After a protracted struggle, Angola obtained its independence in 1975 and then dissolved into civil war as various factions contended for control.
Recorded mintage: 6,000,000 (the vast majority are without mintmark).
Specification: 10.5 g, nickel, 31 mm diameter.
Catalog reference: KM 65, Gomes-E6.04; Vaz-AN.158.
