My late husband worked in high tech in the 70's, 80's and part of the 90's. In going through things in the basement, I'm finding he kept quite a few chips and transistors and other such things. I'm told some of it is scrapable for precious metals. Some of the chips might be collectible in their whole form. How does one know which are best collected rather than scrapped? Searching online has given me a very little amount of information thus far. I'll include some pictures with this post -- just a sampling. There are boxes full of items like those in the pictures -- dozens of transistors alone (every shape size and color).
