We are getting ready to rewire the house. We did the bathroom a year ago and I have the light switches and plug-ins in the shed. I noticed yellowish gold plates in the plug-in. Is this brass or copper. If it is brass, I know it is different from plumbing brass. Are there different grades to brass?

The plugs from cords, are they worth trying to strip down. I cut the wire off as close to them as possible, didn't know if they were worth the trouble or if there was an easy way to do it. Can you just take them in as is and still get something for them?



Also, while stripping wire, some of the wiring I am getting out of small appliances, TVs, and computers are silver in color. I assume this is solder. Should I keep this separate from the rest of the #2 copper that is actually copper colored when I cash it in?
