It's not hard with the excel file. Just limit that column to “Coins.”
I just checked. There are 253,505 coins in the catalog. Adding each sub type gives 252,869 coins. So there are 609 coins in the top level “Coins” type causing problems.
Could someone with database access construct a query to identify those 609 and send me the list? I'll plod through them in my spare time and fix them (or at least make a change request with a guess and let the appropriate referee help).
Lists could also be created for Tokens, Medals, Banknotes, and Paper exonumia, but I'm not volunteering for those unless the lists are very small.
