Hello,
(I already suggested the idea in a thread which was created for discussing a different topic, but I shall express it again in this separate thread for the sake of orderliness.)
I propose to add the Numista rarity index and estimated coin values to the list of search filters and also show them in search results (preferably also with sorting features). By “estimated values” I mean the values which are used to compute the “Estimate for ...% of my coins” on “My coins” page.
These features would be useful for users, which, for example, want to know whether they already have all the affordable and/or popular coins in their collection, but likely they also could be used for different purposes.
P.S.: users who want to express their positive or negative feelings or opinions about the NRI and Numista's estimated values in general should do that in numerous other threads created specifically for these purposes, not here.
