This coin IS double sided but it's kind of fake. I don't know if they are made from real coins or
not, but they sound fake.
Meaning if you drop it, you won't hear that metallic ring you
get from normal coins, you get this dull thud when it hits the table. It looks very real but doesn't
sound real.
This can be used for coin flips, but I know that there are many routines using
this coin.
