Check your cupboards!!!

A collection of Chinese cups carved from rhinoceros horns has become the most valuable find in the 16-year history of the television program "Antiques Roadshow" in the United States.

The five cups, believed to date from the late 17th or early 18th century were valued at $1-$1.5 million on Saturday after being brought to the TV show at a stop in Tulsa, Oklahoma.

The owner, who prefers to remain unidentified, told Asian arts expert Lark Mason he started collecting cups inexpensively in the 1970s and had no idea of the collection's current value.

Chinese antiques have been fetching strong prices in recent years, dramatically increasing the value of the collection.
