I'm a new user, so I apologize ahead of time for any missteps in etiquette (or otherwise). I checked that “This message aims at: ‘requesting the modification of a coin in the catalog'" because it seemed to be the closest match to my request, which is to modify a set in the catalog. I originally made this request through the “Modify or add data on this page” link on the catalog page, and the reviewing user let me know this is outside the scope of that method but suggested I bring it to the forum.
There is currently a listing for the 1971 Eisenhower Uncirculated Silver Dollar Set [N#S3859]. This set was released in 1971, 1972, 1973, and 1974 [see this listing on The Coin Vault and this listing on Collectors' Alliance) . I could not find listing(s) on Numista for years 1972–1974. The 1971 listing includes the silver dollar itself [N#15202] and a blue token [N#142220].
Because of the nature of the way adding a set to inventory works, the current choices (if one has a set from more than one year) are to not add the set for any year other than 1971, have misattributed coins in the primary coin listing [N#15202], or have excess coins in the primary coin listing [N#15202].
I, admittedly, don't know the technological limitations/conventions of the site, so my specific proposal to remedy this may not actually be possible. If it's not, I'd request that listings for the 1972–1974 be added (but I don't think this is the best solution.) My primary proposal is that the set listing [N#S3859] be renamed “Eisenhower Uncirculated Silver Dollar Set." Then, while every set should still include the token [N#142220], the user should be able to select whether their set is from 1971 (with a 1971-S [PCGS# 7408] coin), 1972 (with a 1972-S [PCGS# 7411] coin), 1973 (with a 1973-S [PCGS# 7417] coin), or 1974 (with a 1974-S [PCGS# 7417] coin).
Because it is common to still have the sealed coin + token duo though not the blue envelope, ideally there would be a way to select whether your set still has the envelope without adding the envelope as a separate inventory item (maybe there could be two “variants” of the coin from each year, but the variant would indicate whether the envelope is still present, rather than anything about the coin itself?).
I'm not always confident I've explained things like this well via text, so here is a visual example of what I'm envisioning the page would look like:

My intention is that adding, say, “1972 (With Envelope)” to your collection would populate one blue token on its primary page and a 1972-S Eisenhower Silver Dollar (non-proof, non-variant) on its primary page. [Currently, because 1971 is the only linked coin, the token is added in this manner, and a 1971-S (non-proof, non-variant) is added in this manner.] I love the idea that adding a set automatically adds all the individual coins/tokens to your inventory; I just want to make sure that the proper year(s) are able to be indicated.
I preemptively appreciate any assistance and your patience with a new user!
