George VI Proof Penny 1938 PR66+ Brown PCGS, KM845. A vibrant example with nearly flawless, chestnut-brown surfaces that are drenched in circular patterns of electric-blue and fiery purple iridescence. Wholly lustrous and virtually as-struck, this is currently the finest-known certified example of this date and is absolutely worthy of its superior designation.
