A one-off special following one item from a sunny valuation day at Balbirnie House in Fife through to a specialist auction in London. Presenter Paul Martin is thrilled to find a carved Chinese libation cup that had been sitting in a cabinet for years. On a research journey to discover more about the cup's history, Paul visits the Museum of East Asian Art in Bath and we hear from a dealer about why Chinese art is booming at the moment. The auction's star lot is a rare jade seal that causes a stir in the saleroom - will Flog It!'s cup do the same?
