Nik Stokes - Signed and Sealed X2

A Ziploc bag is closed and placed on your palm.
A borrowed signed coin is placed on top of the bag.
The coin visibly penetrates the still sealed bag.
It is really inside. Really!
And you never touched it.

You repeat the effect.
The coin is positively identified.
You merely throw it towards the bag.
It visibly penetrates again.
It is really inside. Really!
