[AT] Questionable ignition coil

I can remember measuring resistance on coils. I guess I need to look it  up.

Gilbert Schwartz AT List member and Allis Chalmers G owner <vschwartz1 at comcast.net>;I would like to try and delve into the wide knowledge and expertise of the members within ATIS. 
Is there any acceptable method of determining if an ignition coil is good short of installing it on a running engine. Our 1949 AC G would not start a few days ago after being parked for a short period of time. A quick observation determined the contact points were beyond use. I went to the local auto parts store and was advised I probably should replace both the points and of the condenser because they felt like that condenser went first and it caused the points to burn up. With this information I also purchased a new coil even though I wondered if the coil was a bad. 
Bottom line; Is there any way to bench test a coil? We have several used coils laying around here of questionable viability. I would like to pitch them if they aren't any good. 
I appreciate anything you can tell me.
