casjoker-sounds about right for the Wasp.
If its the model I'm thinking it is,the Bearcat with the "K" serial # is a mid 70's bow. without seeing it, and depending on the condition, I'd say $75-$125 generously. If it is in good shape, shoot the SNOT out of it. They are great, durable bows. Great for hunting, 3D, or rendevous'.
Not sure on the Coyote, too new for me to know.
Might I suggest, if you are going to sell, post it up here (in the classified section) instead of the auction site. I'm sure folks here would like to "keep them in the family"
