How can I test this hardware

My uni was throwing away some electronics and naturaly I tried to salvage some. I found this video cards? from the 90s which aparently are retailing from 200 to 400$ on ebay, I am wondering what they are for and how can I test if they still work (to sell them of course) and why such a high price for such an old piece of hardware?
