I have a suggestion for improving the catalog.
Often I use the advanced search to check coins from a country. Nowadays there are so many in the catalog that I ask myself "would I ever find this coin?". For me the main question is: "Should I keep an empty space in my album for that or not?"
So I click one by one to check the Numista Rarity Index. I know in advance, "it is what it is" - not a perfect or accurate tool, but gives a glimpse whether if a coin is scarce, rare or a possible finding. This will help also our collection management, I guess.
You may see my suggestion below. I think that it is not difficult to implement, and "visually" there is space for that. Of course, I would prefer that space filled with the NGCKrause valuations or something, but that is another story.
This would also helps to find out which are the common and the uncommon or rare coins within a country.
