How to Roll a Coin on Your Knuckles

Positioning The Coin and Your Hand

Choose your coin. Depending on the size of your hand and the agility of your fingers, you might want to use a smaller or bigger coin. For example, American quarters tend to work for a lot of people, but you can experiment with different sized and weighted coins to see what works best for you. Bigger and heavier coins may help beginners get better grip and control of the coin. Keep in mind that this trick will require lots of practice. It will take time to coordinate the movements of your fingers while controlling the movement of the coin.

Slide the coin to your pointer finger. Hold the coin in your upturned hand, resting on your fingers. Place your thumb on top of the coin and slide the coin over to the side of the first phalanx of your pointer finger. This is the area right after the knuckle that connects your finger to your hand. As you slide the coin up to your pointer finger, turn your hand over so your palm is facing down.

Position your hand. All of your fingers should be curved downward into a relaxed fist. Your fingers should not be contacting your palm. The first phalanxes of your hand (where you will be rolling the coin) should all be leveled parallel to the floor. Your hand should look like you are holding onto an invisible microphone.

Flipping The Coin

Push the coin onto your pointer finger. While the coin is resting on the side of your finger, use your thumb to push the coin up, on top of your pointer finger. The coin should be resting flat on the phalanx of your pointer finger. As the coin is resting flat on your pointer finger, slightly raise your middle finger above your index finger. Your raised middle finger will act as a barrier so the coin doesn’t fall off your fingers, but it will also be instrumental to flip the coin over to your next finger.

Flip the coin from your pointer finger to your middle finger. With your middle finger slightly raised, simultaneously pull down your middle finger and push up your pointer finger. This opposing movement will cause the coin to grip onto the side of your middle finger, fall into the gap between your pointer and middle finger, and flip onto your middle finger phalanx. When you push up with your pointer finger, you push the coin up and away so it can flip onto your middle finger. When you bring down your middle finger, you provide a lower platform for the coin to easily flip onto. When the coin is resting on your middle finger phalanx, slightly raise your ring finger to get ready for the next flip.

Flip the coin from your middle finger to your ring finger. Once the coin is resting on your middle finger, you will perform the same action as you did with your previous fingers. With your ring finger already slightly raised, bring down your ring finger while simultaneously pushing up your middle finger. The coin will catch on the side of your ring finger, fall into the space between your two fingers, the then flip as you push up with your middle finger. The coin should flip and land on top of your ring finger phalanx. When the coin is resting on top of your ring finger phalanx, slightly raise your pinky finger.

Pinch the coin between your ring and pinky fingers. With the coin resting on your ring finger phalanx, simultaneously push up your ring finger and lower your pinky finger. Try and grip as much of the coin as possible when you lower your pinky finger. Instead of lifting your ring finger up high to flip the coin over, simply allow the coin to fall in the space between your two fingers. Pinch and hold the coin in the space between your two fingers.

Let the coin slide through your fingers. With a portion of the coin fallen through the space to the underside of your hand, loosen the pinch on the coin and let it slide through the space until the majority of the coin is on the underside of your hand. Keep a small, top portion of the coin still pinched between your fingers.

Slide the coin back to your pointer finger. Reach your thumb underneath your palm, to the far side of the coin closest to your pinky. Loosen your pinch on the coin, and use your thumb to push the coin flat against your palm. While keeping your thumb on the coin, slide the coin over your fingers and back up to the side of your pointer finger so you can start again. With enough practice, you will be able to balance the coin on the side your thumb and carry it back to your starting position, rather than sliding it across the underside of your fingers. Eventually, you may be able to roll the coin back to your pointer finger from your pinky finger position, rather than sliding it underneath your hand.

Finished!
