Era

Item Type
Signed Baseball
Condition
Near Mint. Signature is bold, dark, and clear with no bleeding. The ball shows minor handling marks consistent with being signed in-person at a game.
Rarity
Common; actively signing at minor league games, though supply of clean, single-signed items on official balls is relatively low compared to stars.
Overall Assessment
A very clean and bold example of a top MLB prospect's signature. The in-person provenance and stylistic matches make this a solid piece for a Brewers fan or prospect collector.
Authenticity Assessment
Highly likely authentic based on recent 2024 exemplars and provided in-person context. Confidence level 95%.
Signature Style
Stylized modern monogram featuring a prominent 'C' that flows into a 'P' with a horizontal strike-through and a sharp upward trailing stroke. Includes the jersey number '2'.
Signature Characteristics
Fluid, fast motion indicating a practiced hand. Heavy pen pressure on the initial downward stroke of the 'C'. Connected letterforms with a horizontal trailing dash through the center.
Ink & Medium
Blue broad-tip permanent marker (likely a Sharpie) on a synthetic or recreational-grade leather baseball.
Item Description
Unbranded or recreational-grade souvenir baseball with 'CHINA' and factory code 'EKLK4' stamps. Red stitching. Non-ROML (Official Major League) ball.
Estimated Value
$15 - $35 USD based on current status as a prospect. Professional certification could stabilize the higher end of the range.
Comparison to Known Examples
Matches 2024 Wisconsin Timber Rattlers team-signed items and individual prospect cards. The formation of the '2' and the 'P' exit stroke are identical to verified examples.
Authentication Tips
Look for the distinctive crossing of the 'P' loop and the sharp, fast upward stroke on the exit. The inclusion of his number '2' is a common contemporary trait.
Certification Recommendation
JSA (James Spence Authentication) or PSA/DNA 'Witnessed' or 'In-the-Presence' authentication if done at a show, or standard review for in-person pickups.
Red Flags
No significant red flags. The signature shows natural speed and flow without the hesitation common in forgeries. The marker type and location match minor league signing habits.
