I'm the "rookie" card guy, and even I'm confused

"earliest card" or "first card" or "rookie/pre-rookie" all work for me. Personally, I'd rather have one of Jeter's 1992 minor league cards over his '93/'95 Topps "rookies". Or for the daring, try going for his 1982 Oakwood Little League Team Photo! Haha! Yes, it's all a game to jack up the price. I am paying that price.
To me, it's all about researching interesting and esoteric sets that no one else knows or cares about. I prefer the oddball to the standard Topps/Bowman issues. For instance, I just "discovered" Joe Torre's earliest card (or what I believe to be his earliest card). I always assumed it was the '62 Topps. But lo and behold, I was searching eBay and found a postcard from 1961 produced by LL Cook Co. that was postmarked in 1961! Hallelujah and eureka!! I don't plan on re-writing the books, but it's fun for me to have a checklist that no one else is pursuing - even all those "rookie" card collectors out there!
Great thread, BTW. Would love to learn more about when "rookie" cards became mainstream.
