Comparable 1987 San Bernardino Spirit Ken Griffey Jr. minor league team issue cards with in-person or authenticated autographs sell intermittently on eBay, ranging from $150 to $350 based on the grade and authentication certificate.
Condition Details
Slight corner rounding and minor edge wear visible on the dark blue borders, typical of older minor league issues, though the surface appears clean inside the holder.
Grading Recommendation
Recommended for authentication and grading (specifically PSA/DNA for the autograph and card condition) due to the high value of Ken Griffey Jr. signed vintage minor league items.
Card Description
Features a young Ken Griffey Jr. in his San Bernardino Spirit uniform playing in the California League as an outfielder. The border is dark blue with 'SAN BERNARDINO' on the left and 'SPIRIT' on the right, with his name and position 'KEN GRIFFEY JR. Outfield' printed at the bottom.
Notable Features
Includes a blue ink in-person or team-acquired hand-signed autograph across the image. Features Ken Griffey Jr. during his minor league career prior to his legendary MLB debut.
Authentication Notes
The autograph appears consistent with early Ken Griffey Jr. signatures, but professional authentication from a third-party service like PSA/DNA, JSA, or Beckett is strongly recommended to verify the in-person signature.
