In Switzerland, the state-owned Swissmint says today that a 2.96-millimeter (0.12-inches) gold coin created with Albert Einstein’s face on it is the smallest in the world.
The coin, shown above, weighs 0.063 grams (1/500th of an ounce) and has a nominal value of 1/4 Swiss francs ($0.26).
From the Associated Press:
Swissmint said the coin, of which just 999 have been made, will be sold for 199 francs with a special magnifying glass so owners can see the famous physicist on its face.
