CoinWorld - Bidders were willing to pay multiples of published estimates Dec. 18 to acquire certified U.S. gold coins from the Sierra Madre Collection offered by GreatCollections.

The Sierra Madre Collection, according to GreatCollections President Ian Russell, was assembled by its unnamed consignor primarily in the early 1990s during a bull numismatic market.
