The 1863 Seated Liberty Dollar Proof is one of the great Civil War-era rarities in American numismatics, with a tiny proof mintage of just 460 pieces, the lowest since 1858. As the Civil War diverted precious metals from circulation and sharply reduced demand for silver coinage, very few Proof dollars were produced, and it is believed that fewer than half survive today, with only a select handful preserved in such lofty condition. This magnificent PR64 Cameo PCGS CAC example is a truly stunning near-Gem, boasting deeply mirrored fields that contrast beautifully against frosted design elements to create exceptional cameo eye appeal. The obverse displays razor-sharp detail throughout Liberty, while the reverse features a boldly impressed eagle with crisp feather definition and outstanding reflective brilliance. Both sides are remarkably pristine, with radiant silver-white surfaces and only the most trivial signs of handling, placing the coin on the threshold of Superb Gem preservation. The PCGS Price Guide values the issue at $10,000, while the CAC Price Guide stands at $14,500. Population data confirms its elite status, with PCGS reporting just 16 examples in PR64 Cameo and only 6 finer, while CAC has approved only 10 examples at this grade with 5 finer. A tangible product of one of the most pivotal years in American history, this extraordinary Proof was struck as the nation was engulfed in the Civil War, making it both an exceptional numismatic rarity and a remarkable historical artifact.
