The Dukes Of Hazzard | Season 3 | Episode 23 | (The Canterbury Crock)

Episode aired April 10th, 1981

There's more to widow Partridge's old $25 vase than meets the eye. Bo and Luke purchase what seems to be a worthless, damaged vase, only to learn (upon having it appraised) that it is worth $100,000. It soon becomes a race to protect the suddenly valuable artifact when a crook approaches Partridge for the vase ... and later Boss when he learns of its value. Rosco has the most success retrieving the vase, but his clumsiness ensures that the priceless antique will soon become just a worthless old vase.
