1857-S $20 Spiked Shield S.S. Central America MS66 认证号03566903, PCGS号70000

1857-S Gold $20 Liberty (Type 1) MS66 Ex: S.S. Central America { PCGS-SSCA } (Apr'2008) Variety 20-A, Spiked Shield. A superlative example of this renowned shipwreck issue with wonderful orange-gold coloration to complement its gorgeous luster and enormous eye appeal. Preserved over 130 years submerged 8,000 feet in the Atlantic Ocean, this piece appears as it left the mint in San Francisco, with smooth unmarred satiny surfaces and boldly rendered devices. Although sea water and wood can create an acid which will damage gold coins, the calcium rich deposits on the ocean floor of this wreck site neutralized the acid and protected these coins. This is the commoner spiked shield variety with its prominent raised die gouge on the reverse in the field to the left of the lower shield, and visible in the photo. Over 5,000 1857-S double eagles were aboard when the ship sank; while, about half that number have been graded by PCGS and attributed to this wreck.
