Great Britain
William IV bronzed Proof Penny 1831 PR65 PCGS, KM707a, S-3845. Coin alignment. A well-preserved example for this popular type, exhibiting subtle luminosity to the fields that at first glance appear thoroughly patinated with sumptuously dark coffee, but reveal an undercurrent of localized aqua and magenta tones at the flick of the wrist.
