Searching through my fathers old stuff I came across a Webley tin filled with screws etc.

I vaguely remember it from the early 70s, its a .22 tin with ".22 special wasted pellets" written on it, its white and orange with the Webley name written through it in black.

Does anyone know if these are collectable? or is it only fit for screws and bits as my dear old dad decided many years ago
