Howling Coyote Earrings Wild Dog Silver Southwestern

Silver plated - jet black enameling with copper howling coyote covered with epoxy. The measure 1" long - oval shaped. Never worn - tad bit of tarnish but do polish up. Butterfly backs. Interesting for me because they don't stick to a magnet. I bought these a long time ago perhaps 25 years ago and don't recall them being sterling so I'm listing them as plate.
