Where Hoops Collectors Come Together

The basketball card market is driven by star power, draft buzz, and nightly highlight reels. On Mantel, you'll find collectors who follow every game, every trade rumor, and every price swing. Share your pickups, debate draft classes, and connect with people who understand why a Prizm Silver matters more than a base card.

From Luka and Wemby to LeBron and Jordan — Mantel's basketball card community covers every era, every product, and every price point. Whether you're building a set, chasing a specific rookie, or flipping weekly — this is where you belong.

See What the Community Is Buying

Post your latest pulls and see what other basketball card collectors are watching. Which rookies are surging after a breakout game? Which parallels are undervalued? What are experienced collectors loading up on during the All-Star break?

The NBA season is long and full of buy-low windows. Mantel keeps you connected to collectors who spot them first.

One Feed for Every Marketplace

Stop juggling tabs. Mantel aggregates real-time basketball card listings from eBay and Fanatics Collect into a single searchable feed. Find Prizm Silvers, Optic Rated Rookies, Select, National Treasures, and Immaculate cards — all filtered by player, set, grade, and price.

Connect your eBay seller account to showcase your cards directly to basketball card collectors on Mantel.

Comps That Keep Up With the Market

A player's hot streak can double a card's value in a week. Yesterday's comps might already be outdated. Mantel gives you real sales data and current asking prices side by side — so you're never working with stale numbers when you buy, sell, or make an offer.

Track Every Price Swing

Mantel's market trends show how basketball card prices move through the season — from summer league hype through the playoffs and into the offseason. Spot momentum early. Buy during slumps. Sell when demand peaks.

Advanced analytics measure what price alone can't tell you: liquidity, buyer demand, and real trading volume. Know whether a card is truly hot or just relisted at higher prices.

SLAM Scores: Separate Hype from Demand

Every draft class generates excitement, but not every rookie delivers in the market. SLAM scores measure actual sales activity, price trends, and liquidity — giving you an objective view of a card's market strength. High SLAM score? Collectors are buying. Low score? The hype may not match reality.

Wish List Alerts for Every Chase Card

Hunting for a specific Prizm Silver or a numbered Optic parallel? Add it to your Wish List and Mantel notifies you the moment a matching listing appears. Set it once and let the deals come to you.

The Must-Know Products

Panini Prizm — Prizm Silver rookies are the gold standard for modern NBA collecting. Every serious basketball card collector starts here. Color parallels (/25, /10, /5) and autos drive major value.

Optic Rated Rookie — Clean, popular, and widely collected. The entry point for many new collectors and a core piece of any basketball card portfolio.

National Treasures RPA — Rookie Patch Autographs with low numbered print runs and game-worn material. The premium tier of NBA card collecting.
