Ken Griffey Jr. Minor League and Pre-Rookie Card Guide

Ken Griffey Jr. came into professional baseball with a hype largely unmatched by any player before or since. It did not take long for people to realize the value that surrounded "The Kid" and many rushed to capitalize by producing cards of the young phenom.

The following list documents the Ken Griffey Jr. minor league and pre-rookie cards. To keep things simple, the cards are capped at 1988, due to his official rookie cards coming in 1989. The Ken Griffey Jr. rookie card guide can be seen here.  Most of these cards have print runs in the 10,000 to 15,000 card range, but lower numbers are noted when known.

Unlicensed Ken Griffey Jr. Minor League & Pre-Rookie Cards

The problem arises when knockoff cards are presented as official and unknowing collectors are taken for a ride. When dealing with early Ken Griffey Jr. cards, one key thing to look for is graded copies from reputable grading services. Chances are good that if you cannot find a graded version, it is likely a knockoff. Also, there are instances where signed versions have been authenticated by PSA/DNA. It is important to realize that PSA is only authenticating the signature, so some unlicensed cards have certified authentic signatures.
