Vintage Rare Heart Streamer Earrings

These cool Rare Vintage Heart Streamer Earrings are in good previously loved condition. Cleaning out my moms jewelry box again and deciding to let these beauties go. Not sure the metal type but guessing they are silver or silver plated since they are tarnished a bit. Earring backs are mismatched. See pictures and feel free to ask questions and make offers. Dangle style with stud!
