worth saving original tires to 69L78

[black69]

I got to the point of wondering why I keep 3 worn out firestone wide oval F60 14 tires that came with my 69 L78 camaro. I bought the car from the original owner and he told me those were the original tires. Why they survived for a long time was because he put H60 15 on corvette ralleys on day2 in back and then alternated use of the 14" ones that were in back to the front over the years.

Is there any value to keeping these to prove anything of how the car was built? white letter vs redline or something like that? judging maybe?
