Vintage 1960s Playboy Bunny Charm

This a rare find for its age, and I was shocked to learn it is from the 60s early 70s possibly. It isn't signed 925, but I do think it is silver. based on my own experience and just the way it has tarnished, it's easy to see it is old silver use my code - BRANDEEB2316 - Get $15 off your first purchase with Poshmark
