Hello, Guys. I haven't been monitoring the ebay market, mostly due to my busy summer work schedule. I hope that for all of us, things will turn around. User quality tools have always been a good seller for me, and I try to (buy) sell only USA made tools. Collectible woodworking tools go to Donnelly's auction. Machinist tools are also a good seller on ebay, whether user or collectible. I am not very knowledgeable regarding collector quality wrenches. I find anything that may appeal to collectors is heavy, so I try to group by maker or category, and use the large flat rate boxes.I have accumulated 1000's of tools to re-sell, everything has been paid for by selling a few items from each group, the remaining items are the potential payback. . Good luck to all, Lou
