Description
2017 Topps Series 2 Christian Yelich base card featuring a bold, blue felt-tip on-card signature. The card depicts Yelich in his Miami Marlins home black jersey in a batting stance. Note: This is an IP (In-Person) or TTM (Through-The-Mail) autograph, not a factory-issued Topps Certified Autograph.
Key Features
Features the 2018 NL MVP in his original Marlins uniform. Large, clear signature across the mid-section of the card with excellent ink flow.
Authenticity Indicators
Signature matches Yelich's standard 'CY' loop formation and pen stroke speed. High confidence in signature authenticity, however, the card lacks the official 'Topps Certified Autograph Issue' stamp, confirming it is an aftermarket signature.
Flaws to Note
Visible corner wear on the bottom right tip; slight white chipping on the bottom edge; slight left-to-right centering bias; surface contact marks common on paper stock sets.
Selling Guide
Where to Sell
eBay is the best platform for this card due to the high volume of autograph collectors. Facebook sports card groups dedicated to the Marlins or Brewers are also strong options.
Selling Tips
Submit to PSA/DNA or JSA for autograph authentication to significantly increase buyer confidence and price. Mention 'In-Person Auto' in the title. Use a penny sleeve and top-loader for shipping in a bubble mailer.
