Any ideas what they bring I think they are from the 70's early 80's

Kip, are you talking Bear?

If so, I think prices are all over the place, but I've seen nice ones w/o tears and good zippers go $100-150.  

As they say, they are worth what someone is willing to give.

Sounds like your talking about a hard case. Like  Lon said prices are all over the place. Condition has a lot to do with it.

most are missing the interior foam that adds value some guys collect circa cases for circa bows
