Roki Sasaki
Japanese Professional Baseball Pitcher · Baseball - MLB / NPB
Chiba Lotte Marines / Los Angeles Dodgers (Conceptual)
Era
Modern Era - circa 2024-2025
Item Type
Custom Baseball Card
Condition
Good to Very Good. The card shows significant surface scuffing and scratches across the glossy finish, likely from poor storage or handling. The signature itself is bold and clear.
Rarity
Uncommon in this format. While the player signs in Japan, 'Dodgers' themed items prior to an official move are largely fan-made or aftermarket creations.
Overall Assessment
This appears to be a fan-made 'fantasy' card signed (or purported to be signed) by Roki Sasaki. While the signature exhibits natural flow, the unofficial nature of the card makes it a 'novelty' piece rather than a blue-chip investment.
Authenticity Assessment
Uncertain - requires professional authentication. This item appears to be a custom or 'fantasy' card using a manipulated image, which raises significant authenticity concerns regarding the signature.
Signature Style
Stylized monogram scrawl. It features a large looping initial followed by a descending flourish, characteristic of many modern professional athletes signing under time pressure.
Signature Characteristics
Bold, fast strokes with heavy ink saturation. The signature exhibits high velocity, suggesting it was signed by hand, though authenticity of the source remains the primary hurdle.
Ink & Medium
Black thick felt-tip permanent marker (Sharpie style) on a glossy card surface.
Item Description
A 2024/2025-themed Topps custom or unofficial 'fantasy' card featuring Roki Sasaki edited into a Los Angeles Dodgers uniform. The card includes a 'Rookie Debut' date of 3/19/2025.
Estimated Value
$20 - $50 (As a novelty item). Without a legitimate professional authenticator's COA and given the item is a custom/unlicensed card, the market value is limited to novelty interest.
Comparison to Known Examples
The loop structure bears a passing resemblance to Sasaki's simplified 'quick sign' often seen on team-issued memorabilia, though it lacks the specific kanji or number '17' he frequently includes.
Authentication Tips
Compare with NPB-era Chiba Lotte Marines authenticated balls and cards. Look for the specific loop transition Sasaki uses between his initials. Examine the ink for 'stop-and-go' marks which indicate a slow forgery.
Certification Recommendation
PSA/DNA or Beckett Authentication Services (BAS).
Red Flags
The primary red flag is the item itself. It is a custom/fantasy card with a future date (3/19/2025), which is frequently associated with 'through-the-mail' (TTM) forgery attempts or fan-made creations sold as authentic.
Provenance Notes
Essential for this item. Documentation of how a player signed an unofficial fan-made card before officially joining the MLB team depicted is crucial for future resale.
Historical Context
Roki Sasaki is famous for pitching a perfect game in the NPB at age 20. This card anticipates his highly rumored move to the Los Angeles Dodgers.
Market Trends
Demand for Sasaki is extremely high as he is considered the next major Japanese star to transition to MLB. However, the market for 'custom' signed cards is significantly weaker than official Topps/Bowman releases.
Investment Potential
Low. Because the card is not an official licensed product, it will unlikely hold long-term value compared to an official MLB rookie card signed under contract.

Display & Preservation
Store in a PVC-free top loader or a magnetic 'one-touch' holder. Keep out of direct sunlight to prevent the black marker from fading or 'ghosting' onto the card surface.
Interesting Facts
Sasaki is known as 'The Monster of the Reiwa Era.' His autograph habits have become more restricted as his international fame has grown.
