1867 Indian Cent. Proof-66 RB (PCGS). A pleasing mix of gold and reddish-tan patina engulfs the obverse, the reverse displays shades of royal-purple, crimson and golden-tan. Deeply reflective fields overall, even the most minute details are struck to full definition. Just a few microscopic carbon flecks are visible on the obverse, however that lack of any contact marks puts this coin firmly in the Gem grade level..
