1857-S $20 Liberty PCGS MS63 Deep Mirror Prooflike. Variety 20A with Spiked Shield. Ex: S.S. Central America. SSCA 3907. This coin could very well be considered THE ULTIMATE COLLECTABLE regular issue coin recovered from the shipwreck of the S.S. Central America and most certainly a contender for a “first strike” coin if there ever was one! PCGS does not list the population figures for the S.S.C.A. coins, instead they are all listed under number 8922, especially those examples originally certified with the gold foil insert.
Instead, we look to the CAC population report and see they have endorsed 4 coins all at the MS63 level, of which this is one of them. The last time any S.S.C.A coin was publicly offered for sale on the market was in 2000 when the group was first released. This coin has been off the market since then.
