Stamp Collecting
Which is the world's most valuable stamp? How do you start a stamp collection? What does 'fine, average condition' mean? When was the world's first postage stamp introduced?
Hunter Davies , born-again collector and prize-winning Stamp News columnist, and Barry Peachey , Director of Stanley Gibbons Ltd, unhinge themselves and get stuck into your questions.
In the Chair Sue MacGregor.
