Value varies quite a lot. On ebay most things bring 10x reality bc of the large audience. I pick up MT drills when I see a decent bucket of huge/tiny at the flea market for a few bucks bc I've got machine tools and adapters that allow me to use them and I've already got most common sizes. I've probably got 1k of them that I doubt I have $100 in. Not to burst any bubbles or be rude but realistically MT drills/tools are plentiful, hobbyists prefer straight shank, and folks in industry usually buy prefer new cutting tools so IME there arent too many interested buyers.
If you decide to list them you probably want to break them into lots based upon the taper size. The taper angle on morse taper tools is dam near identical between tapers, the various tapers basically just get fatter. MT1 is pretty skinny, MT6 pretty dam fat. Google says there are MT0 and MT7 but not sure Ive ever seen those. What youre posting in the pics is likely MT2. I've personally got MT1 tools that are <0.100 and MT4 (or 5?) that are up above 2". Not sure how to suggest listing drills thatve had the shanks turned straight but I wouldnt toss them, new drills are too dam expensive for that.
