Another thing to look for is on the dryers if you take the drum out from the top quite often you will find loose change in the bottom of the dryer (usually better than half the time). It may only be a coin or two, but I have found almost $20 in change in one and about $15 in another, so you never know. Some folks have found an occasional small piece of jewelry (I have found 2 gold filled, no solid yet). Also, save your small pieces of scrap steel/iron, and when you are ready to scrap the washer or dryer, throw the small pieces in the drum. Needless to say will add weight, and gives you something to hold the small pieces.
