Overpaying for a card is avoidable. Here's how to use Alt Value, Instant Pricer, the Great Value Filter, and cross-marketplace search to know exactly what any card is worth before you buy or sell.
Whether you're looking to buy graded sports cards online or selling from your collection, knowing what a card is actually worth is the difference between a great deal and a costly mistake. Alt gives you the pricing data to make every move with confidence.
Alt Value: Market Pricing, Powered by Data
Alt Value is Alt's computer-generated valuation for each card — built by aggregating real transaction data from dozens of auction houses and marketplaces. It updates daily. Every Alt Value comes with a confidence rating: Low (limited data, wider range), Medium (more defined range), or High (extensive data, precise estimate).
Instant Pricer: Scan Any Card, Get Comps in Seconds
Open the Alt app, tap the camera icon in Browse, and snap a photo of any PSA or BGS graded card. Alt pulls recent transaction data and Alt Value estimates immediately — so you can make a call right there at the card show, in a shop, or at a trade table.
Great Value Filter: Find Cards Priced Below Market
The Great Value Filter scans fixed-price listings across Alt's exchange, eBay, and Fanatics Collect — surfacing cards priced below Alt Value. Three bars = top 1% of deals. Two bars = top 2%. One bar = top 5%. Enable the Great Value toggle in the Fixed Price tab and save your search to get notified when new matching cards drop.
Search Across 13+ Marketplaces at Once
Enable "Include External Assets" in Browse and you're searching across eBay, Goldin, Lelands, MySlabs, Fanatics, and more — all from one place. Real-time pricing, transaction history, and market trends in a single view.
