Graded Value
PSA 9: $60-90; PSA 10: $125-175; BGS 9.5: $80-110 (Note: Pre-production proofs are niche and often valued similarly to standard 1/1s but rarely command high-end premiums).
Comparable Sales
Recent Leaf Valiant 1/1 proofs for top-tier college players trade between $35 and $100 depending on the player. KC Concepcion is a rising star, putting this toward the upper-mid end of that range.
Description
This is a rare 1/1 Pre-Production Proof of NC State star wide receiver Kevin 'KC' Concepcion from the 2024 Leaf Valiant series. The card features a vibrant pink 'Valiant Spirit' design with high-action photography. As a pre-production proof, it serves as a unique collectible representing a stage in the card's manufacturing process, clearly marked with the '1/1 Pre-Production PROOF' label on the front.
Key Features
1-of-1 scarcity designation; Pre-Production Proof status; top collegiate prospect for NC State; visually striking Pink parallel design.
Authenticity Indicators
Authentic Leaf Valiant branding and typography; correct 'Pre-Production Proof' font and banner; standard Leaf card stock thickness. High confidence (95%).
Flaws to Note
Visible centering issues (heavy to the left side); potential for internal surface scuffs common in Leaf's thicker laminate stock; top loader appears scratched which may hide minor surface issues.
Selling Guide
Where to Sell
eBay (Auction with a higher reserve or Buy It Now/Best Offer) is the best platform. Specialized Facebook groups for NC State sports or NIL/Leaf collectors would also be effective.
Selling Tips
Do not grade. Proof cards generally do not see a significant value increase from grading compared to the cost. Use keywords like 'NC State Wide Receiver', '1/1', and 'NIL'. Photograph the card outside of the top loader (in a clean penny sleeve) to show the surface clearly.
