Two new features just dropped to help you track down what you’re after and stay sharp on what’s moving in the hobby.

Want List (Mobile App Only)
Chasing a grail? Missing that last piece for your rainbow? Or find something cool on the feed you want? Add it to your Want List and Mantel will search for it across multiple marketplaces so you don’t have to.

There are a couple easy ways to add collectibles to your Want List:

• From the feed tap the new “Want It” button to add it directly to your list. We’ll take it from there and start hunting.

• Want to add manually? Just head to your Profile menu, tap Want List, and enter the item you’re searching for.

Mantel SLAM Score (Mobile App Only)
The SLAM Score (Secondary Liquidity & Momentum) is Mantel’s way of showing how easily a card can move on the secondary market. It blends transaction activity, price stability, and market supply into a simple 0–100 score.

Higher scores mean stronger liquidity, faster sell-through, and more stable pricing.

(Currently available for graded cards only.)

We know it’s not perfect, it's the first iteration. That’s where you come in. Search for some cards, review the SLAM scores, and poke holes in what we might be missing. Your feedback will help us fine tune it and make it as accurate and useful as possible.

Give these features a try and let us know what you think. We’re building this with the community and your input is what makes Mantel better.

Join Our Beta Program
We’re looking for 10 active Mantel members to join our Beta program. If you buy and sell 20+ cards each month, love trying new tools, and are down to share feedback, we want to hear from you. Send a DM to @MantelHQ to apply.

One of the best parts of collecting, is the hunt. The one card, the last piece, the missing link. Starting today, that hunt will get easier.

We’re launching the Mantel Marketplace beta, and while it’s an early version, we think it’s a big step forward in helping you track down what you’re looking for.

What’s in this beta version:

• Search listings across eBay + Mantelpieces tagged ‘For Sale’

• Bookmark listings you want to come back to (or finally hit that “Buy” button)

• Import your eBay listings to give your cards more eyes and reach

  • To enable this:

    • Go to your Profile, select the About tab

    • Scroll down to the Social Accounts section, click the pencil icon

    • Toggle on eBay, sign in to your eBay account

No more bouncing from site to site. It’s all going to come together.

Coming soon:

• Add more marketplaces (yes, we’re already working on it)

• Create a Want List — tell Mantel what you’re after and get notified when it hits the market

• Smarter analytics to help you buy and sell with confidence

• Improve listing your collectibles in the Mantel Marketplace

This is a beta. It’s not perfect yet. But we wanted to get it into your hands early and start shaping it with your feedback.

We want to hear from the community, what’s the hardest part of finding the items you’re after? If you’ve got ideas, share them in the comments. We’re listening, and there’s a chance we’ll build it into Mantel.

Because in the end, every collection is just a few good finds away from feeling complete.

Just wanted to take a minute to shoutout the Mantel team! This new Update is awesome, and I am enjoying the dark mode! And there was some controversy with the post update last time, but I love the way they handled it! Shoutout to @MantelHQ! Keep up the good works, guys!

We’ve rolled out a few new updates and have more on the way. Here’s what’s new and what you can expect.

Dark Mode is Here (Mobile App Only)

A long-requested feature is finally live. You can now switch to Dark Mode for a more comfortable browsing experience. Just tap your profile icon in the bottom right corner and toggle it on from the menu.

Following Feed Sorting

You now have the option to sort your Following feed by Recommended or Latest. To access it, tap the Following tab, then tap the sorting icon on the right to choose your preferred view.

The Recommended feed will stay as the default but we’ll continue improving it so you can see more of what you love while still discovering new content and collectors across the platform.

A Quick Note

We know things have been a little quiet, but we’ve been heads down building a few new features designed to help collectors grow their collections. These new features will launch in beta and we’ll be experimenting with them, so your feedback will be key to making them even better.

To get the latest update, simply restart the app or tap the Update Now button when prompted.

Thanks for your patience and for being part of the Mantel community. There’s more to come.
