I believe I may have figured out my confusion. Variety vista is listing multiple designations of the coins. For instance 1964 DDO-002 is one, PR-2-O-V-CCW is another and FS-101 is the final. With this in mind I was able to figure out the key here: http://www.varietyvista.com/01c%20L...20System.htm
CONECA's system will take some getting use to, but I like how it works so far.
