Martin beat me to it

Thank you very much for the speedy responses very much appreciated.

The only problem with spreadsheets is you still have to be able to read the coins. In this case many people would have trouble with the M since Nicomedia tended to crowd the M to the point that the middle could be read N. Also many folks fail to realize that the MNE is a match for MNA, MNB etc. since those last letters are just workshop numbers in this case. That is where spreadsheets that list the shops are easier for beginners than using the actual catalogs (RIC) whose authors assumed users would understand that the MNA header included the other letters. While I agree spreadsheets are great tools I remain of the opinion that you are risking error any time you derive a catalog number without actually looking it up in the actual book that assigned those numbers. That is why I prefer saying that this coins is a Nicomedia, shop 5 rather than saying RIC 121 until I have looked at that particular reference to see if their is something lurking there that I should know. In this example, there is not but that is not always the case.
