Producing coins from empty hands can't get much easier than this. 

With Hold Out 52 you start clean and end clean leaving you with just your four coins to continue with you favorite coin routine.
"What you're about to see in the preview shown below is old footage of an effect called Hold Out 52.
Several years ago， I was looking for a way to roll up my sleeves， show my hands empty and start producing coins without using any sleight of hand or elaborate clothing restrictions. Hold Out 52 was the answer! I hope that you will find that Hold Out 52 could be that answer for your next coin production， too". - Michael Boden
