Valuation
Raw (Ungraded) Value
$0.25 - $1.00
Graded Value
PSA 8: $5-10, PSA 9: $15-25, PSA 10: $45-60. (Note: Grading costs usually exceed the value for this specific card unless it is a guaranteed Gem Mint 10).
Comparable Sales
Recent raw sales on eBay have ranged from $0.50 to $1.50 plus shipping. PSA 9 examples have recently sold in the $15-20 range. The market for this card is stable but very low due to extreme oversupply from the 1992 production run.
Description
This 1992 Upper Deck card features a young Bret Boone in his Seattle Mariners uniform during his 'Diamond Debuts' rookie season. The card showcases the classic Upper Deck white border design with the Diamond Debuts logo at the bottom left and the Upper Deck hologram logo at the top right. Boone is shown in a mid-swing follow-through action shot.
Key Features
True Rookie Card (RC) of a 3-time All-Star and 4-time Gold Glove winner. Part of the popular 'Diamond Debuts' subset within the 1992 Upper Deck High Series release.
Authenticity Indicators
High confidence. Includes the standard Upper Deck anti-counterfeit hologram on the reverse (implied by set). The typography and logo crispness match factory standards. This card is not a frequent target for fakes due to high production volume in the 'junk wax' era.
Flaws to Note
Visible centering issues (shifted to the right); top-right corner appears slightly soft; minor 'white' chipping on the bottom edge against the dark background. The surface may have typical factory print lines associated with early 90s Upper Deck gloss coating.
Selling Guide
Where to Sell
eBay (as a 'Buy It Now' or part of a player lot), COMC (Check Out My Cards), or in a local card shop's 'dollar bin'.
Selling Tips
Do not grade this card unless you are certain it will score a PSA 10, as the grading fee is much higher than the card's market value. Best sold as part of a 'Mariners Team Set' or a '90s Rookie Lot' to maximize shipping efficiency. Use 'Standard Envelope' on eBay to keep shipping costs under $1.
