People who believe they have a valuable artefact get a chance to sell it to four of the country's leading buyers. But, once they turn down an offer, there's no going back...
Members of the public hope to sell their prized possessions to arts dealers, and are forced to gamble their offers in an effort to make sure they receive the best value. The first would-be sellers bring with them a collection of Christmas cards from Lady Diana, an original 1960s Dalek, a cigar once owned by Winston Churchill and a Francis Bacon portrait that was nearly destroyed by the artist.
