From the pictures, looks like many used tubes in recycled boxes. Not necessisarily bad (why would anyone save them??) Good idea to inventory, make sure tube inside is same as label, and test if you can borrow a tube tester. You could have several winners. Many tubes have cross purpose used in TV, radio, and audio gear and have value. Most used exclusively for TV mostly are virtually worthless because there are so many of them and almost no demand.
If you are curious, you can use the tube data lookup on this link to get a general idea of usage for most tubes:http://www.nj7p.org/
