Here is a coin that can be very useful in numerous circumstances,
like bets for instance, but also for some magic tricks.
So you will be able to perform predictions but also to complete your routines.
For instance, after splitting a one euro coin into two coins, you want to join them back. Unintentionally, the restored coin has two reverse sides!!
This effect has a very strong impact and can be very funny. And of course the coin can be given for examination.
