Forgive me if this has already been discussed - I searched and did not see any.
I would like to request to add the estimated value of the coin based on the grade I select (this would the number used to calculate the estimate value on My Coins page). This option would be added on the export option page under Column>collection section. I recommend the value for a single coin just as it is in the chart on the coin type page. If I had multiple coins I could do a simple formula to get the total value.
Additionally please consider adding:
Numista rarity index number
Numista reference number
