Old Tubes Found

[Blockhead]

Found these in my parents attic. I know absolutely nothing about tubes, so can anyone tell from these pics if these are worth anything?
Some of the boxes have "good" ,and "used", on them, although I don't think the boxes match the tubes.

Mostly TV tubes with no mainstream audio applications (some people like to experiment with TV tubes, but largely for the challenge/they can be picked up for dirt cheap). The only exception I can see is the 5U4 which is a common rectifier tube, common enough though that value is fairly low (maybe $5).

The 5U4's always andy to have around if it is good.
What's that last tube on the right (sounds like a horror movie title!) in the second photo. I see that copper strip inside and I'm wonderin' if it is a 5AR4 (aka GZ34)!?

This is a GE 5AR4 - these are useful in many later vintage vacuum tube amplifiers and are not inexpensive used or NOS (new, old stock).

... and, in case the OP didn't know, the last two gizmos on the right in the first photo are light bulbs.

Writing looks like 6DA4 to me, which of course begs the question what tube is in front of the 6DA4 box?

Thanks for all the replies so far. It figures, they're for TV's.
