Antiques Roadshow Asian art appraiser James Callahan stunned Jinx Taylor — and made her extremely happy — when he estimated her collection of Chinese jade was possibly worth more than $1 million. That beats the previous Roadshow record of $500,000 last year in Palm Springs, Calif., for a 1937 abstract painting. Taylor brought the pieces to the taping in Raleigh, N.C.; her collection was from the Chien Lung reign from 1736-1795. Callahan said the value of the pieces depends on the market for them in China. The government often wants to buy back such pieces.
