The team visit Burton Constable Hall near Hull. Objects inspected by Fiona Bruce and the experts include the first transatlantic airmail letter, brought on the plane piloted by Alcock and Brown in 1919, uncomfortable diaries of an SS officer imprisoned in Britain in World War II and letters from the founder of modern nursing, Florence Nightingale.

The award for most curious acquisition of the day must go to a bronze figure which was swapped for fish and chip suppers. And one family bring in 1,500 shoe buckles obsessively collected by a late husband. His investment proved to be a wise decision, however, when expert Judith Miller delivers the valuation.

Fiona Bruce and the team head to Caversham Park near Reading which, since World War II, was home to the BBC's Monitoring service, where many news stories have been broken by the team who listen in to international broadcasts. It is a busy day for the experts who specialise in written documents, as they examine items such as a very rare booklet containing notes made in the 17th century by one of Shakespeare's earliest readers. A chunky gold ring complete with a moving letter tells the story of a British family that joined the Californian gold rush in search of personal fortune in 1848. But star item of the day must go to some beautiful watercolour illustrations made in the early 19th century depicting people in southern India. After being told the jaw-dropping valuation, a stunned owner tells viewers that he promised the grandchildren an ice cream if the illustrations were worth more than £100.
