The mini coin! Is made from a special melt containing silver that was carried to the moon on the flight of Apollo 14!
So if I did the math right, each one would contain 0.077 grains/0.005 grams of space flown silver. Cool!
A space medal from my father's golf buddies gave me 2 of these medals... where 25% of the metal was flow in space...
Nice one. Such medals are called relic medals. I have one of the USS Olympia that has some metal in it from the propeller.
I found two of those in a big bulk bag of tokens I bought a few years ago. Neat pieces. And yes, "relic medals" are fun. I had not heard the term used before, but it makes sense.
MINE IS FROM THE FRIGATE CONSTELLATION . IT IS COPPER AND WAS STRUCK "FROM PARTS OF THE FRIGATE CONSTELLATION THE FIRST SHIP OF THE U.S. NAVY"
Technically you go back far enough and all the metal on Earth was flown in space, inside a stellar nebula, and go back further and it was all inside the core of one or two massive stars that went boom! All metal is "space metal".
