Care of the string and straightness of the arrows will be good indicators of the use/abuse it's had. Depends on the model of Bear bow that it is as to what it's worth. I certainly wouldn't give more than $100 for a package like that of an older (80's) vintage Bear. It'll be a slow dog in comparison to today's bows but they killed deer back then and they still will now, they just may not be as dead as my BowTech kills them.
