Since the recovery of sunken treasure began decades ago from an 1857 shipwreck off the coast of South Carolina, tens of millions of dollars worth of gold has been sold. But scientists, historians and collectors say that the real fortunes will begin to hit the auction block on Saturday in Reno. For the first time, hundreds of Gold Rush-era artifacts entombed in the S.S. Central America, known as the "Ship of Gold," will go on public sale. A few of the items from the pre-Civil War steamship, which sank in a hurricane on its way from Panama to New York City, could fetch as much as $1 million.
