Fwiw, it can still be a lot of fun reading the backs of cards, esp. from a historical angle (with vintage) and a player evolution angle (with modern). Some of the super excited descriptions for early Trout cards are a real hoot, for example.
On a different note, a downer for sports cards as a collectibles investment (vs., say, OA) is that value is totally dependent on how/if a player is remembered. Trimpe is no Kirby, but his IH 181 cover is immortal for as long as Wolvie "exists."
Basically, there's no "historical significance" aspect with 99.9% of sports cards independent of the player; Honus Wagner a rare exception. Which is why I sense that many vintage cards (and all cards eventually become vintage) actually lose / will lose value over time as all but the legendary players are gradually forgotten.
