magic is all about playability
the most popular format is commander, which allows MOST cards from the inception of the game
some of these cards can get reprinted, but others are on the "reserve list", which means they won't get printed anymore
that haven't added any cards to the RL in couple decades, so most of those cards have already gone 20-30 years without a true reprint
up until about 2010, they made exceptions to the rule for special foils given out to judges, which is the case for the two in the pic above (Judge Foil - Reserve List)
only a few JFRL cards out there, and an even smaller subset that are playable in commander
as for the cards off the RL, they can still maintain value if they're highly playable
for example, the cheapest mana vault you can find is about $50 for a damaged foreign white border copy
the value for non-RL cards comes in rare versions of playable cards. not sure what the goin rate is at the moment, but there's a Fallout variant of Mana Vault that goes for $2k+ last I checked
If the tcg market continues to thrive, I think the new card value is going to in "universe beyond" special prints of highly playable cards - see also, Spongebob Squarepants Smothering Tithe.
the big risk for a lot of cards is WOTC reducing the playability by printing more powerful cards or by banning the playable cards or other cards that synergize well (see Mana Crypt, Dockside Extortionist ban 2024)
