Vacuum Tubes

I believe that some people on this group collect and sell tubes. I have
several hundred tubes that I want to sell to someone who advertises in a
local shopper newspaper. About half are NOS in their boxes. The rest are
loose and may or not be new. I have checked nearly all on my tube tester
and all apper to be good. I think most are either TV or radio tubes. I
long ago removed anything that I could use in a jukebox. What price range
should I expect to get for these. I realize that some tubes are worth far
more than others but I want to ask for a reasonable price if he wants me to
set the price and what is a fair offer from him.
Thanks, Brian
