Since I just found this site and joined I will try my question here. Where can I go to find the value of larger open end and box end wrenches.  I don't know much about tools, just to love to buy, clean, swap, trade, sell and collect interesting old tools. Selling at flea markets helps keep my collection within the budget my "WIFE" sets for me. But we know the truth, right guys?

Probably the best reference is the 'advanced search' on ebay.  Put in the Keyword 'wrenches' and scroll down to where it says 'completed auctions'. It will give you both sold and unsold.  If you look at enough of them, you can see what sold and for how much and unsold shows you what is too much.  You have to look at a lot of them and mentally throw out the 'flukes' because funny things happen on ebay.

thanks for the reply.  rnb
