While Senators Barack Obama and Hillary Rodham Clinton duke it out in Texas and Ohio on Tuesday, Mr. Obama has trounced his Democratic rival in another arena: trading cards.

Presidential trading cards, released by the Topps Company on Feb. 6 and featuring the candidates’ likenesses and autographs, are fetching high prices on eBay this week. An Obama card, one of 15 made by Topps, sold for $3,122, and a Clinton card, one of 18, sold for $1,325.

Bids for a card featuring an embedded autograph by Senator John McCain, the presumptive Republican presidential nominee, were holding steady at $1,200 in an auction on Monday evening.

The cards are a bonus tucked into packs of Topps Baseball Series 1 for 2008, which retail for $1.99, said Clay Luraschi, the company’s baseball brand manager.
