Man those coin holders look amazing! I'm defiantly purchasing one of those real soon!
As goes for the retrieval of the coin(s) from pocket, I just suggest organize your pockets. Keep your performing coins in one pocket and non performing coins in your other. Other things like a cell phone or something, stick that in your other back pocket since most people put their wallet in their back pocket. And anything else can join the loose change pocket. If you do by chance have something else besides your performing coins in that pocket, while talking with the spectator, just stick your hands in your pocket taking things out as if your looking for something but empty out everything you don't need in the pocket with the performing coins. Stick everything you took out in your other pockets with extra space.
