This is an example of a well made metal & enamel pin.
Too often some pins can be poorly done, but this one is an example of a pin gone right. Notice how no detail is missed, and piercework is used well for the gap between the skates. Both legs and Sonic's tail are distinct. The gap between his arm & body is pitted as well. He has the right number of fingers & the expression still works.By looking at the pin-backing, you can tell this is pretty small, too.
Classic Sonic's shoes have had ice skate blades added, & they've given him a white hockey stick to hold. But why, specifically, a hockey themed pin?
