The Butterfly Coins global experiment: to inspire and track the butterfly effect of random acts of kindness. A beautiful, solid-brass, trackable Butterfly Coin in your pocket is a constant reminder to look for an opportunity to help someone, in whatever way you wish, then give the coin to them with the hope they’ll pay the kindness—and the coin—forward. We believe the butterfly effect of even the smallest kindness started with a single coin can have massive impact over time.
