March is here, and we’re rolling out TWO Mantel March Madness Bracket Challenges. One for the men’s tournament and one for the women’s tournament. That means twice the action and twice the chances to win.

🏆 The Prize:

The winner of each bracket challenge (men’s and women’s) will take home a 2025 Topps CHROME McDonald’s All-American Basketball Mega Box. Two tournaments, two winners—because pulling future NBA & WNBA stars is just as fun as picking the perfect bracket. But that’s not all, winners will also receive a special "Mantel Madness Champ" tag to flex their victory!

🚪 How to Enter:

• Join both contests on Yahoo! Sports Bracket Challenge

• Use your Mantel username as your bracket name (IMPORTANT: Brackets that do not use their Mantel username will be removed and disqualified. Don’t have a Mantel username? Register for one, it’s free)

• One bracket per user per tournament

• Yahoo! Sports rules & point system apply

We just rolled out one of the biggest updates we’ve shipped on Mantel.

There are new tools to help you evaluate cards faster, new ways to understand the market, and a brand new feature we’re especially excited about: the Mantel Prediction Market.

Let’s get into it.

Mantel Prediction Market

Think you know the hobby? Now you can prove it.

The Mantel Prediction Market lets collectors place predictions on hobby questions using Mantel Tokens. No real money required — just your instincts.

Users receive daily Mantel Tokens so you can keep playing and making predictions. If your prediction hits, you earn more tokens.

Here’s how it works:

• Place predictions on players, cards, and hobby trends

• Use Mantel Tokens — no real money required

• Earn Mantel Tokens daily to keep placing predictions

• Win more tokens when your predictions are correct

• See how your predictions stack up against the community in the leaderboard

Got a great prediction idea?

We want the community involved. Users can submit their own market ideas. If it’s a good one, we’ll publish it in the Prediction Market and credit you for the call.

It’s a fun way to stay engaged with the hobby and see who really reads the market best.

Card Lookup

Ever see a card and immediately wonder: what’s this actually selling for? Now you can check in seconds.

Tap the green + button and select Card Lookup. You can search manually or scan a card instantly.

• Use your camera or upload photos

• Scan one card or batch up to 10 cards at once

• Instantly see average sold and last sold prices

• View full market analysis including SLAM Score v2, sales history, pop count, and more

It’s the fastest way to go from card → market data inside Mantel.

SLAM Score v2

We launched SLAM last month. Now it has a full UI upgrade and deeper insights. SLAM helps you understand liquidity and momentum at a glance.

New updates include:

• Visual SLAM Score meter on card detail pages

• Color-coded SLAM badges on graded listings

• Four clear tiers:

• Good as Cash — 90 to 100

• Liquid — 70 to 89

• Inventory — 40 to 69

• Personal Collection — 0 to 39

Because not every card in the hobby behaves the same.

Marketplace Improvements

We also upgraded the marketplace to give collectors deeper insight into the market behind every card.

New updates include:

• Expanded filtering options

• Interactive charts for 30, 60, 90, and 180 day sales

• Redesigned card detail page with:

• Average sale price and full historical sales list

• Population counts across PSA, BGS, CGC, and SGC

• Related marketplace listings

More data. Faster decisions.
