I do not know as I personally check Lincolns, but I would recommend a copy of the Cherrypickers' Guide, Vol. I, which covers main varieties and errors of half cents through Jefferson Nickels.
In the last month, I purchased the 2013 Blue Book, 2013 Red Book, and the Cherrypickers' Guide, Vol I, 5th Ed. Those are just basics. I believe in reference books along with online resources.
The the Cherrypickers' Guide, Vol I, 5th Ed. can be had at Amazon for approximately $25. Well worth it if you are looking for errors and varieties in cents through nickels.
There are tons of varieties and errors and the only way to know is to get a book to peruse at your leisure. No one is being a jerk about this, just trying to point you in the right direction.
