B/W film has to really be old, and/or stored under very hot conditions to show much visible deterioration. The most noticable would be an increase in base fog, which you would notice even out in the sprocket hole areas. This would result in lower contrast prints, but if you scan, you can just adjust the levels and fairly well get back the full tonal range.
Also, you may notice more curling of the film strip, when you cut the film down into strips to put in sleeves.
