You guys are just too hard up for tools or maybe for something to occupy your time. I wouldn't have hauled those home if I was required to clean them up even if they had paid me $10. To each their own, though, I sometimes haul home rusty iron things that appeal to me and electrolytically clean some stuff that anyone else would have thrown in the trash.
If you could go to the scrap yard when I'm taking in metal I'm cleaning out of the shop and ask, you'd get anywhere from a half bucket to 2 five gallon buckets of wrenches like those from me! Anything that I get in a box of tools that doesn't sell on ebay goes into the scrap bucket, and goes to the scrap yard whenever I clean out the shop. That ends up being pretty much anything that isn't Craftsman, SK, Proto, Mac, Matco, Wright, Williams, Plomb or Snap-on. Or anything that isn't in sets of Indestro, Bonney, Barcalo, P&C, Stanley, Penncraft, Blackhawk, Hinsdale, Lectrolite, Wilde, Thorsen, Mustang, Vulcan and similar. If it's made in Taiwan, China, Japan, India, or Pakistan and isn't in a fairly new/nice set, it goes into the bucket without even trying ebay. Sometimes I fill up a flat rate box, and sell the box full on ebay starting at postage plus the ebay/paypal fees on the postage plus a dollar. That's hit or miss, sometimes it sells, sometimes it goes into the bucket. I even tossed an old Snap-on dial torque wrench a while back that was in 9/32" size. Didn't bring $4.99 and flat rate postage in 3 tries, so it went into the scrap metal. Also toss a lot of old files, that aren't worth paying to have resharpened. And lots of dull drill bits, cheap wood chisels, and used bolts. I'm always surprised at the amount of junk that is stored in with assortments of tools I buy to get a few choice pieces that I want.
I find it curious what won't sell; based on what people post that they collect here. I guess they only collect it if they find it for free or nearly so, or if they find it "in the wild".
