I been thinking this same question. I've just threw them into one big barrel, and took them all together. I didn't even look at my last ticket to see what they counted them for. I've noticed post about cutting off the end, and different types, but haven't seen anything special on it. The white thin kind, and gold thin seems to be light, but not sure how to sort it yet, so I just toss it all in. Can't wait for some one to post pic's of the different types, and give some examples of what is worth something. The yards will get ya, if you don't know. My yard takes all my boards, and other electronic scrap. They pay fair prices, and it is only 30 minutes away. Whats crazy, is done of the city close by do, this place is in a small town, and help me sort as I go. Most of it I have sorted, but then we still go through it. Electronic scrap add's of for a good pay day. But you have to know. Still got a bunch of CRT's and old TV's available for someone to pick-up. Still intact and can be loaded with a forklift. For some reason my box stays full here, but not cause I have a lot of messages. If anyone is intrested in about 8 4x4 boxes (standard shipping recycling), of CRT's and old TV's, let me know. Got to move them, and will keep you in business as long as you can keep moving them. I just work with the other.
