Chase, we definitely need more info before we can give you any type of guesstimate. Is it rusted any, how bright and polished is the finish, is the stock in good shape, what type of action does it have etc....
However, Sears sold the Ted Williams rifles by the thousands, so even if it is in excellent condition it will probably not make your mortgage payment for the next month. If it is in safe condition take it out and enjoy shooting it.
