Slot Boston Box (Brass, Half Dollar) by Tango Magic
Show 4 coins in your hand and hand out the coins to be inspected. Put the coins inside the box, take the box and with a snap of the fingers, the coins magically fall into your left hand! Close your hand and magically one coin come back to the box. Repeat the movement with the rest of the coins, and one by one, the coins go back to the box.
This is a beautifully made Boston Box with the added slot-design built in to hold back a coin within the box at will.
