A 6 volt coil, used with no resistor, in the system should test around 2 +/- ohms across the two threaded screws on top. This is the resistance of the wire in the primary windings, there is not a separate resistor in the coil, the windings are the resistance. It is unlikely that the coil has 0.0 primary resistance since this would create a direct short to ground when the points are closed. This would blow a fuse or burn up the wires without a fuse in the circuit. If you don't have a blown fuse or burnt wires then perhaps you have a resister in the circuit. The resistor could prevent the coil from working unless the coil is intended for use on 6 volts with a resistor. The resistance from the center terminal of the coil to either of the threaded terminals should be in the range of 6 +/- kohms (6,000 ohms).
In answer to your question is the coil bad; I cannot not tell from your measurements. I would suggest that you first, determine that you have have power (6 volts) to the distributor terminal with the points open. With points closed the distributer terminal should become ground (connected to ground).

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family�s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
