Today i got bored and before i knew, i had this special coin. It is easy and fun to make. It has no practical application but it is a good conversation starter.
Step 1: The Swap
First, you will have to remove the center part. This can be done with a hammer and a chisel: place the coin so that there is some space under the center part, now give it a good tap and the center will come out.
Now the 2 euro is dismantled, lay the 2 cent coin on the ring and give it a tap with the hammer. The special coin is now finished.
If you did the process carefully, it is possible to get your 2 euros back.
