This is *real* money. From space.
 
On July 16, 1969, the world watched as a Saturn V rocket launched Neil Armstrong and Buzz Aldrin to the Moon. Exactly 55 years later, the students of Earth to Sky Calculus launched the US Mint's limited edition Saturn V dollar coin to the stratosphere on board a cosmic ray research balloon. At the apex of the flight on July 16, 2024, it floated 121,665 feet above the Sierra Nevadas of central California.
 
You can have a single $1 coin for $49.95. It weighs 8 grams of 6% zinc, 4% manganese, 2% nickel, and 88% copper. You'll also receive a greeting card showing the coin in flight and telling the story of its journey to the stratosphere and back again.
