1820 Capped Bust Quarter. B-4. Rarity-2. Small 0. AU-55 (NGC). CAC. OH. Originally and attractively toned from years spent in a numismatic holder, it is difficult for us to imagine a more desirable type candidate from the Large Diameter Capped Bust quarter series at the Choice AU grade level. Bathed in a blend of dominant steel and pewter gray patina, both sides reveal exquisite iridescent undertones of cobalt blue, antique gold and pale rose as the coin dips into a light. Nearly full satin luster is noted, as are design elements that are boldly defined overall. Thoroughly PQ for the type, issue and die pairing, and worthy of the strongest bids.
