Hello! As other members have noted, these appear to be mostly value-based knives. If you wanted to determine the specific value of each, going to Amazon or eBay 'sold' listing search and searching for the specific name printed on the knife and the type of knife (e.g., "MTech fixed blade knife" or "Buck fixed blade knife") can yield exact prices when you find the matching model. That said, with the exception of perhaps the Buck, Kershaw, and SOG models, I would also recommend selling most of these in lots of perhaps 5 to 10 knives, and an auction site like eBay would probably be the best for this in my opinion.
Bit of advice concerning the sold prices:
Ignore the highest and lowest (allegedly) sold for prices. They were flukes. Also, the high may have been a shill bidder running the bid up. Some scummy sellers are known to bid on their own items using a second or even a second and third eBay account to raise the bid, if there is one genuine bidder, to make him or her think one or more others want the item..
If the seller shilled the bid too high, and the legitimate bidder drops out so the shill bid wins, the seller gives that account positive feed back, and the "winning" shill account gives the seller positive feedback, then relists the item.
The advise above to list them at "9.99 no reserve" is close to "on the money".
Make it "$9.99" or "$9.95" no reserve, to make any bidders think they are getting a "deal", plus ... what is it? $6.95 for a small postal flat rate box? Why should you pay shipping?
Include "will combine shipping" in your listing. One or as many as you can squeeze into the flat rate box costs the same to send out.
The above advice to hang onto a couple to use in the kitchen, or to take along if you hike, camp, fish, or hunt, is also good advice.
Many years ago I inherited a couple things from my paternal grand father. Being much younger and stupider than I am now, I traded those things off.
What I traded for are long forgotten, and long gone.
Anyway, I have nothing physical to remember him by now, and regret that very much.
Not being able to pass something of his on to my kids ("This belonged to your great grandfather ..." (or add a "great" if given to one of my grand kids) isn't really a big deal, since he passed when I was eight.
