Some pretty nice connectors

[orvi]

I decided to share these photos of the best yielding material known personally to me in category: pins

снп34 USSR connectors - looking barely mid-grade, shooting more than 30g/kg Au
Local old TESLA black WK stand back with "just" 10g/kg Au.

That said, one female connector yielding more than 0,4g Au I am still wondering why they did this. This isn´t any special series of this connector, any MIL spec. nothing "unusual"... Regular connectors. Some types more than 40g/kg... But, I am happy

Connectors have been my favorite material to date. Those look to be some damn fine pins.

You do not find this scrap very often, as old USSR appliances here weren´t that prevalent since we had a domestic factories here. Which produced also fine connectors (some aiming higher than 14g/kg, average around 8), but nowhere 30g/kg

Personally, I much more like old ceramic ICs - very little metal and very good gold content. Effective, low acid consumption... Cleaner work but with 3% gold pins, I can´t complaint
