Depends on the type. Many TV and radio tubes are worth little because
they're still very plentiful. Certain types, such as 1L6 or 45, are in
demand because they're scarce. In the radio market, those two types would go
for a minimum of $20 apiece if NIB. Audiophiles are also on the lookout for
certain types of tubes and will pay a premium for them.

If you make a list, you could send it to Antique Electronic Supply,
http://www.tubesandmore.com/ and see what they would offer you for the lot.

You could also contact the nearest radio collector club and ask for advice.
There's a list of clubs at http://www.antiqueradio.com/clublist.html . Maybe
someone in the club would want to buy the whole lot from you.
