You can't sell Mount Everest. I think you could try to sell this roll for an interesting price. Imagine a collectioner needing an old virgin roll to complete a vintage "kit" (camera + film, maybe in a nice wooden box with red felt, that kind of stuff).
In any case I think that keeping it in its virgin form would be much more interesting that trying to take pictures on it which probably would not come out well anyway. IMO it's like trying to cook with a 60 years old bottle of wine, to see what comes out.
