The black bodied resistors in the upper right with long gold plated leads can sell individually up to $12 EACH. They often have very tight tolerances, and are used in high precision test instruments. Hobbyists like them too - using them for calibration in a home lab.
The gold-tabbed transistors (three leads, with gold tab at top, two bags upper left, plus six individual transistors) are Motorola MPSU-series devices, and genuine ones can sell for $6-10 each. Note that any coming from China are likely counterfeit, so you can ignore the Chinese eBay sellers.
Sample search: https://www.ebay.com/sch/i.html?_nkw=MPSU05 (there are about 20 individual types....MPSU01 and up..) Even if house marked (non-Motorola number), they likely will sell just as easily.
The 4-legged bridge rectifiers at upper center are worth about $1-2 each, nothing special.
Aside from the precision resistors and the MPSU-series transistors, I see nothing special (without seeing device markings, unable to with images posted...). For gold content, again, very little in the collection you have.

Thank you VERY helpful!
I bought out a electrician engineers estate with thousands of these things mostly leg packs and small resistors. A few HP transformers that weigh a ton! Sound stuff. Wish I knew more about it all lol
Thank you :roll:
