An apprasal record was set on The Antiques Roadshow. The episode airs in January 2010. Trapper Cramer, a North Carolina-based artist, 59, and his wife, Jinx Taylor, discovered that four pieces of carved jade that they own (click photo to enlarge)--passed down to them from Jinx's father--are of Imperial character and date from the Chien Lung Dynasty (late 1700s).
Appraiser James Callahan appraised them at $710,000 - $1.07 million, conservatively.
A record set in October 2008 still stands: for the most expensive single firearm ever sold at auction. "A Colt Walker pistol [and powder flask], made for use in the Mexican War, and considered to be one of the finest examples in existence, sold for a spectacular $920,000." The pistol and flask were issued "at Vera Cruz in 1847 to Private Sam Wilson, a Texas Ranger." (Click photo to enlarge.)
