Remove no mint mark coin on checklist

Can we remove the listing for the no mint mark coin in the checklist? If someone actually has one of these, it's an error, and should not be listed as a separate variety. (It's makes it look like I don't have all the available coins of this design, when I actually do.)

You're lucky not to collect Australia. You have to buy the exact same coin 7 times.
 

We should confirm if it exists or not. There are many errors listed with their own line.  I think one of the solutions to this would be a box to check that you don't want certain lines or an ability to simply create the double check mark of a type. It would cut down on many coins people check off that they don't actually have and messing up the statistics.

A per line check off of “I don’t want this coin/banknote” would be awesome. In the banknote part, there are numerous lines of non-existent banknotes and repeats that the referees don’t bother checking before approval or remove after publishing. It would be nice to have the completed double check mark when you actually do own all varieties but there are non-existent notes listed.
