On Sunday, appraisers from the PBS hit show "Antiques Roadshow" recorded the highest-value collection ever appraised in the show's 15-year history.The big ticket item: five Chinese carved rhinoceros-horn cups dating to the late 17th or early 18th century, which are worth between $1 and $1.5 million. An Oklahoma resident bought the cups inexpensively in the 1970s, according to a press release from the show's producers. The reason the value of the cups is so high is due to China's growing demand for Chinese antiquities.
The episode will air as part of "Antiques Roadshow's" 16th season in 2012. The name of the lucky owner of the cups was not released.
