Shortly before last Christmas, a prominent New York auction house put up for bid a collection of 63 postmarked envelopes and stamps that the daring riders of the Pony Express had carried 150 years ago. Experts estimated that the rare collection, owned by Thurston Twigg-Smith, an 88-year-old philanthropist and former publisher of the Honolulu Advertiser, might net $2.5 million. It drew $4 million.
