You borrow a coin and a pack of cigarettes from the audience. Ask a spectator to sign the coin. Then you slide the plastic wrapping partly off of the cigarette pack. With a quick gesture, the signed coin in your hand will penetrate the plastic wrapping of the cigarette pack! Purely technical and no Gimmick used!
This is one of the best coin tricks on the market today.
It is very fast and very convincing.
Not difficult to implement.
