The effect in the video isn't bad, but I would make a couple suggestions.
I am not 100% sure on the gaff you made, but this could be done without anything besides a switch. I would use regular coins and not poker chips, because by doing this you can make the trick seem a bit more impromptu and gives it a "normal" feeling. (might have to play with the wording depending on the size of the coin)
Either way, the moment when the move takes place needs to be rethought out, it doesn't make sense to put something into your top hand to immediately drop it to the lower hand if the chip was already in the lower hand to begin with. Also, you want to find a way, through movement or patter, to reduce the focus on the hands during that move....not emphasize it like you did in the video, the time you want spectators totally focused on the chip/your hands is when you move the "a"
Nice work so far though.
