1990 Upper Deck Sammy Sosa Rookie Card #265 (Birthdate Error Variant)

Item Overview

  • Item: 1990 Upper Deck Sammy Sosa Baseball Card
  • Card Number: #265
  • Player: Sammy Sosa
  • Team: Chicago White Sox
  • Manufacturer: Upper Deck
  • Dimensions: Standard (2.5" x 3.5")
  • Medium: Gloss-coated cardstock
  • Condition: Mint (based on photos and user-provided statement)
  • Distinguishing Feature: Birthdate error (incorrectly lists 11/10/68)

  • Card Back: Includes stats from 1989 (Texas Rangers) and 1990 (White Sox), with action photo
  • Not For Sale: Item currently not for sale

Authentication Notes

  • Manufacturer ID & Logo: Card displays authentic 1990 Upper Deck branding, including the front logo in upper-left corner and hologram security feature on back.
  • Printing Details: Color alignment, clarity, and centering appear correct for a genuine Upper Deck card of the period.
  • Player Image: Shows young Sosa with White Sox before his iconic years with the Cubs.
  • Birthdate Error: This card contains the incorrect birthdate (11/10/68); the correct date is November 12, 1968. This misprint is documented among hobbyists and contributes minor collector interest.

Market Value (As of Mid 2025)

  • Standard #265 Sammy Sosa Rookie Card (1990 Upper Deck)
    • Raw (Ungraded): $1 to $5 USD
    • Mint Raw with Birthdate Error: $5 to $10 USD
    • Professionally Graded Mint (PSA 9 or BGS 9): $20–$35 USD
    • Gem Mint (PSA 10): $60–$120 USD
    • Note: The birthdate error is not classified as a major rarity or high-value misprint by professional grading companies (PSA, Beckett, SGC), so it adds only a modest premium.

Rarity & Collector Interest

While not rare, the 1990 Upper Deck Sosa card is popular among rookie card collectors and fans of '90s baseball memorabilia. The birthdate error is a minor production oversight and has been noted by enthusiasts, but does not reach the collectible error tier of more prominent print mistakes (e.g., reverse image cards or missing nameplates).

That said, this card captures an early phase of Sosa's career before his rise to stardom during the 1998 Home Run Chase, giving it added historical interest.

Recommendations

If you are considering maximizing value:

  • Grading: Submit to PSA or Beckett for authentication and grading. A PSA 10 gem mint card can sell for over $100.
  • Storage: Keep sealed in a hard plastic case (top-loader or magnetic case) away from UV light and humidity.
  • Insurance Appraisal: If bundled with other early Sosa or White Sox-era memorabilia, consider a formal appraisal for documentation or insurance.

Conclusion

This 1990 Upper Deck #265 Sammy Sosa rookie card with birthdate error is a verified original in excellent mint condition. While not considered a high-dollar collectible in the hobby, it carries modest value, especially if professionally graded, and remains a meaningful piece of baseball history for any collector of ‘90s-era stars.

Estimated Market Value (Ungraded Mint, Mid-2025): $5–$10 USD
Estimated Value (Graded PSA 9–10): $20–$120 USD
