A "hobo nickel" is a nickel that has been inscribed with appealing images. During the Great Depression, poor people sometimes made them to sell, which is how the folk art form got its name.
Shaun Hughes is an artist who makes hobo nickels professionally. We've previously featured some of his pop culture nickels, which include Spider-Man and stormtroopers. For this nickel, Hughes changed the Indian head on a Buffalo nickel to Batman.
