This autographed baseball celebrates the 25-season career of Jim 'Kitty' Kaat, a legendary left-handed pitcher and 1982 World Series champion. As a three-time Gold Glove winner and Hall of Fame inductee, Kaat's signature is a staple for collectors focusing on Minnesota Twins history or elite MLB pitching.
What Is Autographed Baseball Worth?
The typical price range for Autographed Baseball is $100 - $120 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:
- The presence of a Certificate of Authenticity (COA) from reputable services like PSA/DNA or JSA significantly impacts the $100-$120 valuation.
- The physical condition of the baseball, including the whiteness of the leather and the lack of 'toning' or yellowing, preserves the item's market price.
- Signature clarity is vital; bold, unfaded ink signatures command the highest end of the value range compared to bled or faint autographs.
- Special inscriptions, such as 'HOF 22' or '16x GG', can add a premium to the standard collector value.
How to Identify Autographed Baseball?
- Look for the distinct, legible cursive signature typically found on the sweet spot of a leather-covered official league baseball.
- Verify the ink consistency, as signatures from the 1970-1990 era were typically signed with blue or black ballpoint pens that may show slight aging.
- Check for official manufacturer markings from the era, such as Rawlings or Reach, which provided the cork and yarn-core balls used in MLB play.
- Cross-reference the 'J' and 'K' flourishes in 'Jim Kaat' with known authenticated examples from his playing and early broadcasting years.
