9. Tatton Park (1)

Henry Sandon has a memorable day when one of the rarest 18th century pieces of Royal Worcester turns up. Other finds include a box of the world's most valuable and beautiful diamonds, that aren't quite what they appear to be, and an old box of golf balls with a value that's definitely not below par.
