Currently we can add the link to other coin pages (in section References), adding it one by one… I usually add some, like in case where the coin is issued in different metal (CuNi, Ag, Au) so i try to add the two other in reference. If more coins issued in series, I add the series instead of adding multiple references.
However, what in case if the coin is not a part of series (or is part of one series) but refers to another one full series. We have another series that can be used and we can link only to the individual coins in reference field.
My proposition is to allow to add the full series in Reference section.
Example: in 1993 Gibraltar issued the series of silver and gold coins for Japanese Royal Wedding with two Peacocks: https://en.numista.com/catalogue/index.php?ct=coin&se=Japanese+Royal+Wedding&e=gibraltar
In 1997 one of two designs used in 1993 (slightly modified) was used again on different coins with Peacock. N#79965. It was issued with no connection to any event in Japanses Royal family, so this is not the same series. Of course, I can add multiple references but better to add only one link that redirect you to full series from 1993.
