...you would be surprised at what people leave behind and throw away.
It never ceases to surprise and amaze me what people throw away!
By the way, you will get more $ for the tools if you sell them on Craigslist or eBay rather than at a garage sale. Facebook is a great place to sell tools locally, too. I see that you're in Oklahoma.
(Me too!**) You should try posting a couple on the community page I admin: (
https://www.facebook.com/OKC.garage.sale.craigslist/) It has 5,000+ followers who buy and sell second-hand goods and most are in Oklahoma. You simply message back and forth with your prospective buyer, agree on a price then meet the buyer at a safe place like the Sheriff's station to make the exchange. (Read this post:

Also, if you don't have any money in the tools you've found, assuming, of course, that they are simply "used" and not antiques or collectibles with the potential to increase in value, I don't think you need to do extensive research in order to determine an asking price. Modern tools usually have logos or labels advertising the brand and model number. I would simply use that info to search eBay for completed listings of the tool in question to find out what it's brought at auction and (depending on condition) ask the same. (Here's how:
TIP: What's it worth? Use eBay tool to find a fair price | OKC Craigslist Garage Sales - Oklahoma City)
Knock off about a 1/3 if you sell it on Craigslist and a little over half if you want to sell it in a garage sale. When I can't find something on eBay, I Google the retail price and apply essentially the same formula: ask 1/3 of retail on Craigslist and 20-30% of retail at a Garage Sale.
That's the gist of it, anyway. I hope it helps!
Best of luck,
