Hi, I have a pair of my grandpas Ray bans and I’m trying to understand what kind of value they hold? (See attached photos)I am a self proclaimed expert on Bausch and Lomb aka Vintage Ray Bans. I have a degree in Vintage Ray Ban Eyewear, if you need help or have a question this is the place to get answers. I also buy them if you have a pair or more you want to sell. Cheers.
