Sorry, without having any idea what's in it, I can't make a serious offer. Besides, I think I speak for everybody here when I say that "hundreds of tubes" isn't particularly useful unless you want to set up an eBay store or something. Most people would be likely to buy one or two here or there....
My advice is to A. get a conductance tube tester, B. sort all the tubes into piles by type, then get a bunch of those dot stickers in red, orange, yellow, green, and blue. If a tube checks out good, put a green dot on it. If a tube checks out a bit weak (significantly below average for the tube, but still within the green zone), put a yellow dot on it. If the tube tester says a tube possibly needs to be replaced, put an orange dot on it. If a tube tests as bad, put a red dot on it. If a tube checks out as excessively strong, put a blue dot on it.
Next, take the red dot tubes and retest them a couple of times to make sure your tube tester isn't flaky, then pitch them.
Take the ones with an orange dot, retest them a couple of times to make sure your tube tester isn't flaky, then sell them on eBay as a lot of dubious tubes. Be sure to make it clear that they are dubious.
Take the yellow dot tubes and sell then on eBay as individual tubes. Make it clear that they are weak, but should be usable.
Take the green and blue dot tubes and post a list on here and give us first dibs, then put them on eBay as individual tubes.
