Hidden Mickey pins are pins that are produced by Disney that have a Mickey head silhouette detail inserted somewhere in the design. It will be part of the metal of the pin, so the same as the metal which makes up the back and details of an enamel pin

Cast Lanyard pins (also known as Hidden Mickey pins) are only available for initial trade with Cast Members (i.e. not available for purchase) and are identified by a silver Mickey on the pin. Typically part of a series of similarly-themed Cast Lanyard pins, these are sought after by pin collectors due to their rarity.

Other rare Disney pins are completer pins. These are pins that complete a set. While most of the set might be relatively easy to find, there is always one pin that is considered the “completer.” Disney did not produce as many of this pin and makes it harder to find in circulation.
