William IV Proof Penny 1831 PR66 Brown NGC, KM707a, S-1845, S-3845. Coin rotation. A gorgeous proof Penny, chocolate brown with much reflectivity in the fields; the reverse has been double-struck, rather curious for the type. Absolutely needle-sharp details, beautiful to behold and certainly a superior offering from the popular 1831 proof set.
