It’s an old custom in the United Kingdom that when a visitor sees a money tree, he wedges in his own spare change. When you hammer in your coin, you make a wish. These trees are literally covered in the wishes of strangers. Most of the money trees are in Cumbria in West England and Portmeirion, along the Afon Glaslyn River in Wales. The tradition goes back to 18th century Scotland when florins were hammered into trees with a prayer to take away sickness.
