Loyal Vanish by Thinking Paradox

Signed coin to shoe 100% impromptu.

At any moment, you borrow a coin and have it signed on both sides. Now, holding it at your fingertips with your sleeves rolled up, the coin vanishes into thin air without a trace. Your hands are genuinely empty, and there's nothing to hide. But here's the best part: without even moving from your spot, without bending down, and using only your feet, you remove one of your shoes to reveal the signed coin inside! A valuable coin technique that will allow you to create genuine impromptu miracles.
