Speer Nitrex rifle ammunition -- collector value?


Does anyone know if the Speer Nitrex rifle ammunition has any collector value above normal trade/purchase price?

I used to use this stuff for hunting; has an unusual box (20rds, contains 5 or 10rd ‘cigarette’ sleeves). Produced at the Speer factory, various centerfire calibers, not really old stuff though.

I use something different in my -06 now and was curious about the Nitrex.
