Still kicking myself on this one, could've bought an '87 Fleer Mike Greenwell, Ellis Burks, and Todd Benzinger (yes THAT Todd Benzinger) for $10 duriing hte Summer of '88.
. This was before the grading craze and these bad boys were solid NM-MT (or better) with razor sharp/razor sharp+ corners (wow!) with only minor chipping on the edges...
