Terrell Owens' 2004 NFC Championship ring sold for $48,200 in an online auction on Thursday. If the winner pays up, it would be the highest price ever paid for a conference ring, according to ring expert Scott Welkowsky, owner of Out of This World Memorabilia in Mission Viejo, Calif. In fact, Welkowsky says he has sold thousands of championship rings in his 23 years of business and the most a buyer has paid for a ring was $35,000 for a Super Bowl XXIX ring given to a San Francisco 49ers starter. In February, former Patriots backup cornerback Leonard Myers sold his Super Bowl XXXVI ring for $32,600. "You can tell that the person buying this doesn't normally buy rings," said Welkowsky, who recently sold former Philadelphia Eagles owner Leonard Tose's 1980 NFC Championship ring for $6,500. "It's for a good cause and it's certainly a nice piece, but the diamond and gold value in this ring is worth no more than $3,000."
