1991 Upper Deck San Francisco Giants Baseball Card Team Set (Copyright 1990 by The Upper Deck Company, LLC)

Description

This is a complete, original team set of Upper Deck baseball trading cards featuring key players from the San Francisco Giants. The cards are part of Upper Deck's "The Collector’s Choice" series from the 1991 release, which was printed in 1990. All cards are sleeved in protective plastic and housed in their original casing.

The set includes:

• Will Clark (#445)
• Kevin Mitchell (#247)
• Robby Thompson (#178)
• Jose Uribe (#207) – noted as a "birthday error card"
• Matt Williams (#157)
• Team roster checklist card (#79)
• Other cards presumably listed on the team checklist (visible in photos).

All cards are in mint, uncirculated condition, which increases their desirability to collectors.

Historical Context

Upper Deck debuted in 1989 and revolutionized the baseball card industry by introducing higher-quality production standards, including:

• Glossy, full-color fronts
• Anti-counterfeit holograms
• Premium card stock

The 1991 Upper Deck series was one of their early landmark sets, combining sharp photography with clean design. While it was produced in high numbers during the baseball card boom of the early 1990s, mint condition sets that have remained sealed or professionally preserved are less common today.

Of note in your set is:

• Jose Uribe (#207) Birthday-Error Variant – There has been historical collector interest in this card due to an incorrect or inconsistent birthdate. While not considered highly valuable by grading companies, it has attracted speculative demand in online markets.

Authentication

Based on visual evidence:

• Cards feature the Upper Deck diamond hologram, standard for authentic 1991 prints.
• The font, photography, and layout are consistent with verified originals.
• No signs of counterfeiting or reprints are visible.

Authentication Level: Moderate to High Confidence
(Professional third-party grading from PSA or Beckett would confirm this officially.)

Condition

• Mint State: Cards are clean, crisp-edged, and show no signs of wear, indicating they were never circulated or handled extensively.
• Sleeved and cased: The inclusion of protective sleeves and original casing helps maintain long-term preservation and collector value.

Current Market Value

As of mid-2025, approximate values for raw (ungraded) cards in mint condition are:

Card

Est. Individual Value

Will Clark (#445)

$2–$5

Kevin Mitchell (#247)

$2–$4

Robby Thompson (#178)

$1–$3

Jose Uribe (#207 error)

$5–$15 (dependent on demand fluctuations)

Matt Williams (#157)

$2–$4

Roster card (#79)

$1–$2

Complete Set Value

$15–$30 (ungraded, retail market)

Online “Buy It Now” prices can be inflated, but realistic sold auction values land in this range. If professionally graded (e.g., PSA 9 or 10), individual cards could sell for significantly more, especially the Uribe and Clark cards.

Recommendation

If you are considering resale:

• You can sell as a complete team set, ideally on platforms like eBay, COMC, or sports memorabilia shops.
• Grading by PSA or Beckett could increase the value, particularly for the Jose Uribe error card or any card likely to grade 9+.
• Consider preserving this collection as-is if sentimental or part of a larger Giants memorabilia grouping.

Final Appraised Value (Mint Condition, Ungraded, 2025)

$15 to $30 USD (for the complete 1991 San Francisco Giants Upper Deck Team Set).
