$1.00 - $3.00
Graded Value
PSA 7: $10-15, PSA 8: $20-25, PSA 9: $45-60, PSA 10: $250+. Note: High-grade Post cards are rare due to being cut from cereal boxes.
Comparable Sales
Ungraded copies typically sell for $1-2 plus shipping. PSA 9 copies have recently sold in the $40-$55 range. PSA 10 copies are scarce and can command over $250 due to the difficulty of finding food-issue cards in perfect condition.
Description
This 1991 Post Cereal Mark McGwire card features the Oakland Athletics slugger in his iconic home-run-hitting follow-through. Part of the 30-card 'Collector Series' found on the backs of cereal boxes, this card features a vibrant yellow outer border, blue inner trim, and the classic red Post logo. These cards were often hand-cut, making factory-edged specimens highly desirable for collectors of vintage food issues.
Key Features
Produced during McGwire's physical prime; iconic food-brand crossover; nostalgic '90s design; features the 'Bash Brother' in his Athletics uniform.
Authenticity Indicators
Authentic. Features the correct matte cardboard stock typical of Post cereal boxes from the era; correct MLBPA logo in upper right; printing dot matrix is consistent with 1991 offset lithography. Confidence: High.
Flaws to Note
Bottom right corner shows wear; top left corner has a visible 'ding'; right-side edge has significant white chipping where it was likely separated from the box; centering is approximately 60/40 left-to-right.

Selling Tips
Do not grade this card unless you are certain it will hit a PSA 10, as grading fees exceed the value of a PSA 7 or 8. Use keywords like 'Classic Food Issue' and 'Oakland A's' in the listing. Ship in a penny sleeve and top-loader to prevent further edge chipping.
