Unless they come wrapped in original boxes, then that's a hard thing to determine. Even then, you have to take the seller's word for it. If all the digits illuminate well at the rated voltage and current and there's no visible darkening or mirroring (this can be quite obvious in well used nixies), then that's as good as it's going to get I think. There are some used tubes that will still last years and years and some that don't last long at all (IN-1's, IN-2's...in my experience...).
