Switzerland has minted a gold coin so small that a magnifying glass is needed to see each side - one of which shows Albert Einstein sticking out his tongue.

State-owned Swissmint said that the 0.12-inches (2.96-millimetre) gold coin is the smallest in the world. It is similar in size to the combined thickness of two pieces ofpaper.

The coin weighs just 1/500th of an ounce (0.063 grams) and has a nominal value of 1/4 Swiss francs (about 20p). Its weight is comparable to that of two grains of rice.

Swissmint said the coin, of which just 999 have been made, will be sold for 199 francs (£155) with a special magnifying glass so owners can see the famous physicist on itsface.

The famous image of Einstein sticking out his tongue was taken on his 72nd birthday on March 14, 1951.

United Press photographer Arthur Sasse was trying to persuade him to smile for the camera, but having smiled for photographers many times that day, the scientist stuck out histongue instead.

Swissmint said it wanted to push boundaries with the coin and stretch the limits of technology and achieve something unique.

Einstein lived mainly in Switzerland from 1895 to 1914, where he also completed his studies in 1900, at today's ETH in Zurich.
