The coin made by state-owned Swissmint is about 0.12 inches in diameter and weighs 1/500th of an ounce. The coin is so small, it comes with a magnifying glass so owners can view the cheeky image of Einstein.
Its value is equivalent to 26 cents. Only 999 coins were made, with each expected to be sold for around $205.
Einstein was granted Swiss citizenship in 1901 and is the winner of the 1921 Nobel Prize for physics.
"Swissmint drew inspiration from Albert Einstein, not least because of his determination and patience," it said in a news release.
