Hello,
Recently I found some coins whose pages in the Numista catalogue have date ranges in the lettering box, for example: https://en.numista.com/catalogue/pieces908.html
Instead of (ideally, IMO):
IN GOD WE TRUST
LIBERTY
1925
D
We have this:
IN GOD WE TRUST
LIBERTY
(1909-1958)
In all the countries I referee for, the lettering is always the date/mintmark/variant of the coin whose picture is used on the page; if the picture is changed I change the lettering as appropriate. In my opinion this is the most ideal option but I leave it to Jarek to decide whether this should become policy.
