An excellent set of 5 coins for the beginner as well as the more advance. You take one coin at a time off the top of an undetectable stack and place them in your pocket.
It appears that when the coin is removed from the set it immediately returns to the pile. Show both sides of an English Penny & Half Dollar. Put the Half Dollar in your pocket. Open your hands the coins are still there! Repeat, putting the English Penny in your pocket, again both coins remain!! No skill is required the coins do all the work.
