This is a breathtaking beauty, a REAL SUPERB GEM 1866 3CS! The typical adjectives usually used to describe the quality and eye appeal will fail to paint the full picture! You really need to see this coin in hand! The fabulous surfaces are extremely clean and you can only see some light, Mint made die polishing lines with a glass. There are light traces of semi-prooflike mirrors and a strong luster which enhances splashes of original royal blue, vivid violet, and tawny gold on both sides. WOW! Look at all the colors! Every detail is needle sharp and has thick frost. The eye appeal is excellent in every way. Anyone who has followed our auctions knows that these tiny jewels are among our founder, Laura Sperber's, absolute favorite coins. Over the course of her career, she has helped build, and helped sell, many of the top PCGS Registry Sets of this series, in both Mint State and Proof. Her expertise in how each date comes, is close to unrivaled in the industry today. When we say that a Mint State or Proof trime is absolutely superb, take our word for it, and this one is AMAZING! PCGS 11, NGC 4, CAC 7. The current PCGS Price Guide value is listed at $13,500 and this beautiful SUPERB GEM should bring close to that when the hammer falls. Just four examples are graded higher--a slightly finer MS67+ will cost over $20,000, if you can find one! Good luck. Cert. Number 36661377 PCGS # 3686
