Portugal 1930 50 centavos
This specimen was lot 25329 in Heritage sale 3019 (Chicago, April 2012), where it sold for $690. The catalog description noted, "Republic 50 Centavos 1930, MS66 NGC, a superb coin with full mint brilliance and pristine surfaces, rare date and grade." In 1910, Portugal, having ousted her king, dropped the réis and adopted the escudo, divided into 100 centavos. The specimen shown is a better date, despite the large mintage, of a type struck for Portugal 1927-68. It superseded an aluminum-bronze type struck 1924-26 (KM 575) and in turn was replaced by a smaller bronze coin struck 1969-79, after which the denomination was suspended. The escudo was retired in 1999 when Portugal joined the euro. This date, altho not a particularly low mintage, is rare like 1931, 1935 and 1938; prior and subsequent dates are much more available.
Recorded mintage: 1,116,000.
Specification: 4.5 g, copper-nickel-zinc, 22.8 mm diameter.
