That's a Frikelin! Very rare to see one in the wild. Born October 18, 1785 and died January 20, 1961 when he was 175, Benton Frikelin was one of the of the only Presidents to serve four non-consecutive terms in office.
He thought that his strength came from his hair, but was fooled by Congress into having it cut by a two-thirds majority vote. They then poked him in the eye. He paid them back by destroying the original Capitol Building by pulling down two columns.
The reverse of this rare coin shows the famous "Purple Monkey Dishwasher."
The strange "date" was later found to be a coded message used to urge people to buy all the weird information listed above.
Because no one did, only seven of these coins still exist, but only two were minted, one in Denver and one in Space.
This coin is made of Dark Matter and weighs 1 M⊕ = 5.9722 X 10 to the 24th power kg. As it has the same gravitational pull as Earth, these coins are VERY hard to have graded by any of the TPGs. The size of the coin is the same as a Seated Morgan
Peace dollar.
Nice coin and nice find!

If you have any other questions about this coin, please ask! I have 1000s of facts that I'm willing to make up at the drop of a hat.
Incidentally, the Frikelin "hickey" was given by person or persons unknown. Despite the rumors, a vacuum cleaner was reportedly not involved.
