Leaf Trading Cards
Demand Level
Moderate. Demand is high among NC State fans and 1/1 collectors, but slightly capped because it is an unlicensed (non-team logo) Leaf product.

$40.00 - $75.00
Graded Value
PSA 9: $60-90; PSA 10: $125-175; PSA 8: $30-45. (Note: Grading 1/1 proofs often yields lower ROI than set cards).
Comparable Sales
Other Leaf 1/1 Proofs for college stars typically sell between $35 and $100 depending on the player. Concepcion is a rising star, keeping this on the higher end of that range.
Description
Unique 1/1 Pre-Production Proof of NC State star Kevin 'KC' Concepcion from the 2024 Leaf Valiant Spirit series. This card features a vibrant pink/purple background with a dynamic horizontal design and high-gloss finish. Clearly labeled '1/1 PRE-PRODUCTION PROOF' in a sleek white box on the front.
Key Features
True 1-of-1 scarcity; Highly touted NC State wide receiver prospect; Unique proof designation used by Leaf for prototype or pre-release verification.
Authenticity Indicators
High confidence. The '1/1 Pre-Production' stamp is a standard Leaf security and branding feature. Foil logo and card stock thickness are consistent with Leaf Valiant 2024 releases.
Flaws to Note
Minor centering issues common in Leaf production; slight top-to-bottom imbalance. Surface must be checked for 'dimples' common on Leaf chrome-style stock.
Selling Guide
Where to Sell
eBay (Auction) is best for 1/1 items to find the maximum market price, or NC State fan groups on Facebook.
Selling Tips
Do not grade this card; the '1/1' status already establishes its rarity, and grading rarely adds significant value to Leaf proofs. Mention 'NC State' and 'Freshman All-American' in the title.
