This is the biggest feature release week in Mantel history.
Since day one, our goal has been to build the ultimate ecosystem for collectors, a place where community, data, and commerce intersect seamlessly. We believe the future of the hobby isn’t just about buying and selling; it’s about understanding trends, engaging with the market in new ways, and having instant access to information.
This week, we are rolling out three major features that fundamentally change how you interact with the collectibles world.
Here is a look at what’s dropping on Mantel.
1. The Mantel Prediction Market
We are thrilled to introduce the first free-to-play prediction market built specifically for collectibles.
The hobby is full of debates. Will a specific player’s PSA 10 population double by 2026? Will a highly anticipated auction lot break a six-figure record? Instead of just arguing about it in comments, now you can stake your reputation on it.
How it Works: Using Mantel Tokens, you can bet on real-world hobby outcomes. Because prices move dynamically as bets come in, the market acts as a real-time gauge of community sentiment. If you think an outcome is likely, buy “Yes.” If the crowd is overly optimistic, buy “No.”
- Market Types: Participate in both binary markets (Yes/No outcomes) and Winner Take All markets with multiple potential outcomes.
- Track Your Performance: Manage your positions in a dedicated portfolio view and get notified the second a market resolves.
- Compete: Prove you have the best pulse on the market by climbing the leaderboard, checking the activity feed, and sharing your positions via shareable market cards.
It’s a new, risk-free way to engage with market trends and prove your hobby knowledge.
2. The Instant Card Scanner
Identifying a card, finding comparable sales, and determining its SLAM Score used to require multiple tabs and tedious typing. We’ve fixed that.
The new Mantel Card Scanner uses your device’s camera to instantly identify sports cards with a single tap. Just snap a photo and confirm the match. Mantel immediately pulls up matching marketplace listings, average sold prices, price history, and the card’s SLAM Score.
It is the fastest way to know exactly what a card is worth across marketplaces, whether you are at a card show or sitting at your desk.
Key Scanner Features:
- Batch Scanning: Have a stack of cards? Scan multiple cards at once to quickly digitize a collection.
- Scan History: Keep a running history of recent lookups for quick reference later.
- Text Search: The scanner also doubles as a quick search tool if you prefer to look up a card by name instead of a photo.
3. SLAM Score V2 and Marketplace Overhaul
Data is useless if it isn’t easy to understand. We have completely redesigned Mantel’s proprietary valuation system, SLAM Score V2, to give you deeper insights faster.
The new SLAM Score features a clear visual gauge with detailed score breakdowns. Crucially, we’ve added historical trend charts and indicators, showing you exactly how a card’s value has moved over time. See a card you like? Hit the new tracking button to follow it.
A Brand New Marketplace Experience Alongside SLAM V2, the entire marketplace experience has been overhauled for better usability:
- Enhanced Navigation: A new filter bar, autocomplete search with recent history, and smart autocomplete suggestions make finding cards easier.
- Deeper Data: Listings now feature auction countdowns, detailed sales history with price data, population counts, and related listings.
- Universal Search: Search now spans the entire platform. When you type in the search bar, you’ll see results across Posts, Users, Marketplace, Topics, News, and Groups, complete with count badges.
These features are rolling out to all Mantel users this week. Update your app, start scanning your collection, and check out the Prediction Markets to place your first bets.
