I have a dime that is the same on both sides, it is tails on both sides. Is it a trick magic coin, or is it worth alot of money?
It is a trick.
Did you get it from a store as change? If you did, those people are dumb! for not seeing it when someone gave it to you.
Check if it says legal tender though, if it does save it and it could be worth something later.
There is a double headed penny worth around 3million.
