For a time, the biggest card after the 1989 UD Griffey was this 1991 Topps Gold auto:
If I remember correctly it was included in "special" complete sets and at one point booked for well over $100. I got this copy for about $7 shipped.
Some folks have used contemporary stats to argue he wouldn't have made it anyway, but that's all part of the mystique of this story, of guys like him and Prior and countless others. Baseball America had him as a top-20 prospect from 1992-4, #1 in '92 and #2 in '93.
Who knows what would have been? There's only what was.
Have a good one everybody and good night Pumpsie Green, wherever you are!
