The piggy bank dates back farther than you might think. This one, in terracotta - nearly eight inches high - has survived five centuries of annual rattlings and bangings in its native East Java. The Javanese made them as early as the 14th and 15th centuries, about the time that Chinese traders popularised the use of coins. There were terracotta rams, turtles and frogs, too. But pigs are special - they signify prosperity. This one, from a household or village shrine, is on display, priced pounds 3,950, at Spink, 5 King Street, St James's, London (0171-930 7888).
