"I've seen you before," Henry Sandon tells a young owner with a collection of porcelain. The 15-year-old explains that he met Henry two years ago, when Henry advised him to add some Victorian Coronation pieces to his porcelain collection. Previously the young man had only collected Jubilee memorabilia but decided to follow Henry's advice. The owner has now also acquired an extraordinary charger from the 1690s, decorated with the likenesses of King William III and Queen Mary II, who ruled England jointly at the end of the 17th century. Wondering aloud where the owner gets the money to collect such fine objects, Henry says the piece is extremely rare and valuable—worth as much as £1,000 ($1,500). The boy confesses that he does have "a bit of help from my dad," who he says finances most of this hobby.

The owner of a large collection of film lobby cards said it all began with his dad, who used to collect film memorabilia as a boy—a hobby that he passed to his young son. The boy now has thousands of stills, an interesting collection Marc Allum admires, saying it contains some classic cinematic images, most of which were publicity stills issued by the film companies. There is a lobby card from Psycho, which was posted in the foyers of the cinemas. He also notes a picture of Charlton Heston on a Vespa scooter on the set of Ben Hur, looking "rather incongruous" in his outfit. Another photo shows Liz Taylor giving a very sly wink on the set of Cleopatra. Yet another superb image is of Boris Karloff as Frankenstein, asleep and with a cigarette in his hand. Marc says these lobby cards are worth £30 to £40 ($45 to $60) each. He also tells the owner he is "very impressed" with what he's seen of the collection and encourages him to "carry on collecting!"

Roy Butler is shown an outstanding group of medals by a young owner who explains that during World War II, King George VI broadcast to the nation that he would establish a new award to be called the George Medal. Around that same time a man named Leonard Thorne was a policeman on patrol when a bomb went off in a Tottenham Court Road pub. Thorne, along with an air raid warden, risked his life to go in and help people out, and he was subsequently given the new George Medal. Thorne later joined the Royal Air Force and flew 31 missions in Lancaster bombers, each time bringing the plane and crew back intact. For that reason he was also eventually awarded the Distinguished Flying Cross. Roy explains that it is very rare for anyone to have been awarded both a DFC and a George Medal. "This is a wonderful, wonderful group," says Roy. He tells the owner that in the collecting world the medals would usually be worth about £4,000 ($6,000) in total. The combination of the DFC and George Medal for one person means, however, that their value might exceed that number. The medals now reside in a museum and Roy thinks it's wonderful to get to see them in the RAF Museum with an authentic Lancaster bomber in the background.
