The resistance ranges given are correct. Pick up coil resistance will vary greatly with temperature.
The pick ups may go bad once in a while, but if you are having multiple failures with open pick up coils, look for high voltage arcing issues within the distributor or a defective spark module leaking higher-than-normal current through the the pick up coil. The pickup is just a magnetic 'sense' and to/from current should be low microamps (uA).
Worn distributor shafts can cause the reluctor to hit the coil pole.
Wrong angles can cause reluctor/pole collisions when the mounting plate advances, but is OK at rest. If you have to bend the pole piece out of the box, that is a problem.
