This will not be fully known until the commission is deducted by the people handling your estate sale. My guess is that the demand for such things will diminish as less people are interested in anything other than their phones. Maybe break even. Go on eBay and search tool lot. Wrench lot...
This reminds me of a neighbor that asked me a few times if I would like to have some boxed ins that were in his way. I found it hard to believe but I was almost certain he had a couple of reclusive sisters he was fed up with and trying to dump them on me. Well one evening he showed while me and my brother were sitting by the fire pit wetting our whistles. He hadn't much more than sat down when he said "I've got those boxed ins in the truck and will leave them here in case you run into some one that wants them". I thought oh heck, and began blubbering something like I,,,I'm sor,,,, sorry but I just don't have room for them and wouldn't know how to take care of them. My brother jumped up and said "I'll take them". The guy went to his truck and returned with a full set of Snap-On wrenches. That was the first time in years I turned anything down that was free but I won't make that mistake again.
