I generally prefer to stick to the objective pre and post-war card eras to define hobby eras because there’s too much subjectivity involved otherwise. For example, some folks call 1988-1994 the junk wax era and anything after 1994 as modern. But I’m not so sure you can call 25-year-old cards modern anymore. The vintage designation also depends on your perspective (likely your age). Because there are some very cool cards of baseball legends, printed between 1990 and 2002, I’ll casually refer to them as pseudo-modern for the sake of sharing eight rookie cards I think would be great additions to any hobbyist’s collection.
1990 Topps #414 Frank Thomas

There’s no need to break the bank and reach for a No Name on Front variant. Frank’s standard card, in PSA 8, is between $10-20; raw, they’re between $2-4.
1990 Topps #336 Ken Griffey Jr.

I’m going to cheat a little; I know Griffey’s rookie year cards were in 1989, but this card does say All-Star Rookie on it, and I like the look better than any of the 1989 rookies. Gem Mt copies of this Topps card are over $300, but you can get an 8 for under $20.
1991 Topps #333 Chipper Jones

If you have the funds, the Desert Shield variant is a great card, but may I also suggest tracking down a signed copy of Chipper’s Topps rookie? They’re pretty readily available. Either way, Chipper’s #333 rookie card is a classic.
1993 Pinnacle #457 Derek Jeter

The 1993 SP Jeter is a great card, sure, but I prefer the Pinnacle’s look. Also, there are less than 1/3 as many graded 1993 Pinnacle Jeter rookies than SP ones (though there is more incentive to grade an SP rookie, in any condition).
2001 Topps #726 Ichiro Suzuki

Ichiro will be HOF eligible in 2025. He was a 10 Time All-Star and had 200-plus hits in 10 straight seasons from 2001-2010. You could also go with his 1993 BBM card (#239), as that’s his most recognizable Japanese card.
2001 Bowman #264 Albert Pujols

Pujols continues to produce; he’s like a modern-day Julio Franco, who you could see being a designated hitter until he’s 50.
2002 Upper Deck Prospect Premieres #93 Zack Greinke Autograph

Pitchers are never the hot thing in baseball cards, and Greinke’s hobby value is hurt by having been on so many teams, but he’s a HOFer to me, and this card looks incredible.
2002 Bowman #379 Joe Mauer

Mauer is the only catcher with three batting titles, so I think he’s super under-appreciated. Did you realize he’s the only athlete selected as the USA Today National high school player of the year in two sports (baseball and football)?
What other rookie cards between 1990 and 2002 do you think are hobby gems? Let me know down in the comments or over on Twitter.
