If the paper was kept in a cool place, you may be in luck. It'll probably have a bit of "cosmic fog", but even that can be dealt with. As for the chemicals... I bought a bunch of Perceptol that had been sitting on a store shelf since the 1970's, you know, those nice little cardboard cans with the pop tops. I paid a whole dollar for a half dozen cans, so I figured I had nothing to lose. I mixed up a quart and processed a test roll of Pan F+ - perfect!

Some people are like Slinkies. They're really good for nothing, but they still bring a smile to your face when you push them down a flight of stairs.
Even if the paper from a given box proves to be unusable, don't discard it. It should still be possible to fix, hypo clear, and wash it. It can be used for back to back mounting of other prints made on newer paper. Likewise, using the old stuff on the back of a mounted and matted print will counteract any tendency for curl.
I did in fact print some older Agfa papers a few years ago, and they did produce a slightly fogged print. With the right chemistry I'm sure you can make use of them.
The paper had, just like your paper, been stored in a 'cool' place. The prints looked cool the way they did, in my opinion, even though they were probably not tonally correct.
Good luck and have some fun with it!
