You can find money trees in the forests of Great Britain. People hammer and bend coins into trees. It is supposed to bring them good luck, the like, or even cure from a disease. This tradition exists for hundred of years.
The coins are usually knocked into felled tree trunks using stones by passers-by, who hope it will bring them good fortune. These fascinating spectacles often have coins from centuries ago buried deep in their bark and warped by the passage of time. The tradition of making offerings to deities at wishing trees dates back hundreds of years, but this combination of the man-made and the natural is far more rare.
