Identifying a Superbird without a fender tag

Thanks, the car has a 440 six pak with the rear wing and nose cone. The fender tag is missing and the car has been out of service for so long it's out of the DMV system. It was taken apart to rebuild and the owner has lost interest. What do you think the value of the car is without the fender tag?

No clue, would need pictures and proof its real. Is there a build sheet? How about the VIN?
