Description
2018 Topps Pro Debut card featuring Chicago Cubs prospect Jen-Ho Tseng in his Tennessee Smokies uniform. This card features a bold, blue felt-tip in-person autograph across the image. The design mimics the 2018 Topps flagship baseball style with white borders and team-colored accents.
Key Features
Features a former top Cubs pitching prospect; contains an in-person (IP) signature; Minor League Prospect card from the popular Pro Debut set.
Authenticity Indicators
Correct card stock gloss and thickness for 2018 Topps; high-resolution printing on the Tennessee Smokies logo; signature matches known examples of Tseng's 'scribble' style script. Confidence: High (Card), Medium (Autograph, as it is uncertified).
Flaws to Note
Slight corner softening on the bottom left; off-center top-to-bottom; blue ink signature is thick and covers most of the player's torso which may be seen as a negative for aesthetic collectors; potential for surface ink transfer.
Selling Guide
Where to Sell
eBay (low start auction or BIN), Mercari, or COMC. Best suited for targeted Facebook groups for Chicago Cubs collectors.
Selling Tips
Market this as an 'In-Person Autograph' (IP Auto). Do not list as a 'Certified Autograph' as it lacks the Topps guarantee stamp. Use keywords like 'Cubs Prospect' and 'Taiwan Baseball' to attract international interest.
