They have some value, possibly, depending on your position. We used to have a Mac II where I used to work which did menial tasks like imaging non-urgent artwork. This is going back a few years and it was already out of date then. These are very old machines tho, so unless you are in a position like that, you might as well not bother. They'll not be much use for day to day work (altho I was talking to some Russian people the other day and they were all using Quadra 700s as their main machines and servers and whotnot - the conversation was veeerrryyyy ssslloooowwww). If you can get one in pristine condition, it might be worth keeping it as an antique, but for day to day stuff, go for something newer. Remember that they won't run new OSes and so you'll need older software in most cases too.
