It looks like a lot of high speed steel. Carbide is worth more, but hss is fine for most applications. I recently purchased two wooden machinest toolboxes full of reamers, taps, calipers, end mills, tool holders, carbide insets etc. for $300. All of this stuff was u.s. made and in great shape. Used stuff isn't worth very much, but it's great if you have the equipment to run it and if the price is right.
