Appearing in artwork since at least the 11th century, the Green Man is typically portrayed as a human face surrounded by dense foliage.

A whimsical look at the 1950s., this coin features a Poodle skirt on the face with a group enjoying a ’50s themed get together on the inverse.

This set of four micro coins feature fun representations of fire, air, earth and water on the face with a colorful compass rose on the flip side.
