O.C. man pays $3 million for first U.S. gold coin.
The rare coin market is poised for a climb, Steven L. Contursi indicated as he made nearly $1.6 million of the total $5.3 million winning bids in an Oct. 29 auction in Las Vegas, Nev., by Bowers and Merena Galleries.

A unique 1854 Kellogg and Co. $20 pioneer gold piece goes on display again in California, during the first three days of the Long Beach Coin, Stamp, and Collectibles Expo, Jan. 29 to Feb. 1, in the Long Beach Convention Center.
In March, Steve Contursi paid millions for one 1794 silver dollar and more for the collection it was in. But he thought the expensive and surprisingly shiny coin, 40 millimeters in diameter, might be something even better, something no one realized still existed.
