This is one of a set of three years of service enamel metal pins that are exact reproductions of the ones worn by Starfleet on the sleeves of the maroon jackets in the Classic Star Trek movies II-VI. The two round ones are known as pips, the plain one for one year of service and the one with the command emblem for 10 years. The long one is call a squeek and represents 5 years of Starfleet service. Produced by Lincoln Enterprises, the late Majel Barrett Rodenberry’s company (Nurse Chappell and Gene’s widow) many years ago, these have had limited release and are not easily found outside of Star Trek conventions and fantasy shops. It has been stored in a smoke and pet free environment.
