This is incredibly impressive, and easy to do.
You'll need:
One toothpick
One deck of cards
One nickel
One large-sized dinner plate
One coffee mug
1. Place the deck of cards facing downwards on the dinner plate. Meanwhile Place the toothpick in between two cards at roughly 1/3 of the way through the deck.
2. Place the coffee mug on a plate and place the nickel flat on the bottom of the mug.
3. Take out the two cards holding the toothpick and place them in the coffee mug vertically with the nickel. Turn the plate face down on the table.
4. Shuffle the deck of cards and fan them out face-up on the table. Place the mug in the middle of the fanned out deck. Present the audience with both the toothpick and the nickel in the coffee mug. Voila!
