What is it worth? 1966 Goodyear Blue Streak tire.

I have an original Goodyear BLUE STREAK bias ply tire with wheel in the trunk/spare rack of my 1966 Barracuda. It has approximately 90 to 95 % of the original tread. It does not have any cracking. I would rate this tire/wheel as a 9.5 on a scale of 1 to 10. I don't know that I will ever use it, and the judges at the Mopar Nationals didn't seem to be impressed that I had it with the car. Any ideas of what it might be worth?

I doubt that I will ever find three more to go with it, and Coker doesn't make them.
