PSA: This pin was purchased from Jim Coleman Ltd (jimcolemanstore.com) website. When my class and I purchased from this website, EVERY STUDENT'S credit card information was stolen and false charges were made. Prevent this from happening by purchasing your nursing pins from OTHER sellers, this does not have to be me. Silver Electroplate is a thin layer of silver over the surface of a base metal piece. Pin from 2015, Arkansas State University
