1912 Barber Half Dollar. Proof-66 (PCGS). CAC. An attractive and original Gem Proof that must be experience in-hand. Golden and olive patina reveals violet and midnight blue iridescence under direct lighting. Watery and mirrored fields frame satiny and sharp design elements. From a Proof mintage of just 700 pieces. Examples grading Proof-66 or finer are very scarce; probably no more than a few dozen comparable examples could be accounted for. Just 11 coins have been certified finer by PCGS in this category. From the Harrington Collection.
