They can be worth something. How much depends on what they are and on their condition. What are they?
If you can figure out what they are, look for completed sales of lenses like your friends' -- same make, trade name, focal length, maximum aperture -- in barrel on eBay. No guarantee you'll find any, but its your best chance.
Them shutterless / barrel lenses ain't worth a plug nickel !! Trust me and if ya' don't then let that Jim Galli guy tell you just how worthless they are---!! Being it's Christmas and I feel it's better to give than receive I'll help solve your dilemma! Pack em' all up and ship to me and I'll even pay the shipping!! Send me them Artars and Dallmeyers and I'll even take a foreign one or two --you know that Nicola Perscheid lens!!
Seriously there are plenty of users here of the shutterless/barrel lenses-send me a list and we'll post the left overs here!!
Merry Christmas
