I saw comments that Boardsort would only buy BNC as dirty aluminum,
I have some Clean Gold mini BNC connectors, (no center pins or plastic) How do I classify them to sell?

They are likely gold pin connectors. That design is majority 100:1 (1/100) gold on copper-nickel 70:30 bronze—with a 1-4% gold content in the base mix.


That said, can you crush it between your fingers

At that thickness any real alloy of gold should bend fairly easily .
If you can bend the tube into a circle… you’ve got a gold alloy far higher than GPC and worth further discussion.
Otherwise you’re safe with gold pin connectors class

You have five fingers (if not, I apologise).
Place one between the second and fourth, middle/index on top of it. And apply pressure.
Yes it’s slightly painful
If it bends into a U you have a gold alloy
If it bends with a seam, making a sharp v, it’s a bronze
