Silver Coins from the SS Central America

While gold grabs the public mindshare like nothing else, the recovery of silver coins from the most recent SS Central America salvage effort is remarkable in its own right. At the recent ANA convention, Bob Evans spoke to the Liberty Seated Collectors Club on the silver coins recovered from the SS Central America. These pieces survived in amazingly original condition (many were certified by CAC) in what is normally a harsh, corrosive environment for silver objects. Bob explains the science of this surprising preservation and enthusiastically conveys his continued fascination with this bit of American maritime history.
