George VI Proof Penny 1940 PR65 Red and Brown NGC, KM13. Highly attractive, with stunning red-brown surfaces that present oil-slick iridescence. An extremely rare date with a reported mintage of only 5 pieces. At present time, there are only four certified examples in existence, this one by NGC and three others by PCGS. Even so, this is the only coin with a red-brown designation.
Estimate: 2000-2500 USD
