You could make a list of what cartridges and styli there are and then advertise them here in the classifieds on VE with some ballpark prices...Are you into music at all personally, ihavenoclue?
IF you are, you may want to get yourself a nice turntable and learn as much as you can about it...This place is as good a place as any to get some solid information AND we're a lot friendlier and more patient! At least, I seem to think so! Maybe your dad left you some nice audio equipment, since he had so many quality cartridges and styli (or as you say styluses...)???
In any case, you might want to keep a couple cartridges for yourself and divest yourself of the rest...I'm sure if you listed what you have, there would be more than a few takers here and you would know that they're all going into the right hands...I'm sure your dad would be proud to know that! If you want to know more about turntables, read many of the threads here...Lots of good information for newbies on up to more experienced collectors and enthusiasts...And don't forget, you can ask anything of the Engineers here...There is bound to be SOMEONE here with an answer for you!
Don't be a stranger and let us know what you decide...We're here to Help
