SEPTA token sold between 1990 and 2003 to school students that we've made into a necklace. They measure 3/4s of an inch in diameter, just a bit smaller than a regular token.
For this Central High Grad, they bring back not-so-fond memories of waiting in line to buy a bag, and then barely receiving a discount! A surefire conversation starter.
Multiple pieces are available all in similar condition to the token jewelry pictured.
