I see that that this suggestion has been brought up in multiple threads but seems to have never actually been considered, not sure why that is
It would be nice if we could sort our collection by the Estimate field to get a general idea of our coins values. Every other coin collection site out there already has this feature, so it would help to bring Numista into feature parity with the competition. It should also be trivial to implement since this data clearly already exists in the backend since you can export your collection to a spreadsheet and see those values. It would be nice not to have to export my collection every time I would like to check that.
