Junk gold, silver, diamonds and copper, its everywhere.
The Lions Club was famous for collecting no longer used eyeglasses on drives. They provided vision enhancement for many that couldn't afford it, they still do.
The Pair in the photo without lenses are 12kt, low grade but still refineable.
The other pair are pince de noise, or pinch the nose. 22 Kt and I'm converting them to polarized sunglasses.
Also pictured is a heavy copper "Arthritic copper bracelet" popular in the 80's.
The Ladies watches are gold filled, the Company Fob solid 24kt.
All the other bric brac has little value, gold plated, gold filled.Small bag of diamonds removed from jewelry. On a bed of Euros.
Many of us have junk valuables piled up in boxes and scattered.
If it is a usable piece, like the sunglasses, bring it out and use it. Collect the rest and separate and identify it.
My Uncle Mickey bought bags of this stuff from Pawn Shops in Miami in the 70's, it was his job.
I was fascinated while he picked through it wearing a monacle and squinting.
In Miami at that time many rare watches in various need of repair was scrapped for gold and silver.
Uncle Mickey taught me the Trade. Miss him.
