Hi
This is troubling me for a while now and it feels like such dashboard would add to Numista another true edge. When visiting local insanity coin fairs in Slovenia (the prices went totally off rails lately), I am often checking year lines of coins I have or do not have in collection. This is rather slow process, as you literally have to search each coin separately and by being an old geezer by now, using stupid smart phone is to some extent quite a nuisance. Its just easier to go sit at a coffee shop. Often I see those really old school collectors carrying printed tables on paper and checking coins. Its all so inefficient.
Well I would like to see one day Numista having standard circulation dashboard of coins (of selected issuer), which are in use at a date of accessing this functionality. For my humble Turkish collection of coins this would look like this:

or like this

This is a mega cool super fast way to see which mintage I generally do not have yet. It seems to be applicable also when visiting another country.
Furthermore down the road it would be also nice to have a possibility to select the Year or Ruling authority, by which new set of coins would pop-up in dashboard. This could be useful when searching through dead issuers or ruling authorities.
I propose staring with Denmark first. 😎
