What to do with Organ Tube Find? 44ish Tubes (untested)

I was given 44ish Conn Organ tubes from an old organ. I have not tested any of these. I was just wondering what to do with them? Should I sell them "as-is" how to I find someone to test these to see if they work? Are they even worth selling/keeping? 🙂

Thanks!
 
It's a bit hard to see what you have here, but if the 5U4GB, RCA 6L6GC's and 6V6GTA's are in good condition, those should be worth something.
The small ones with clear tops could be broken, but could also have side getters. If there still is silver getter flash on the glass, they still have vacuum. Doesn't guarantee they work though.
Do you have a list?
 
Those clear tops have side getters. I don't see anything wrong with these tubes. Common audio tubes. My experience with ex-organ tubes is generally positive, private owners usually didn't play their organs too much. Most likely they are like NOS, but of course can't tell without testing.
 
Yup. Side getters. Plenty of people like to pay extra for "clear tops"...

RCA made 12A*7 tubes like that and I see one tube at least that says 12AT7 so I'm guessing the tubes in the middle are all 12A*7
