Collectors, get a tool built for you.
Know what your collection is worth, to the day
Live market values for every book, aggregated from multiple marketplace sources and refreshed automatically. Total collection value updates in real time as prices move.
Catalog in seconds, not minutes
Open the iOS app, point at the cover, and Stash identifies the book. No keyboard, no spreadsheets, no manual entry.
Make smarter grading decisions
The slab calculator tells you whether a book is worth sending to CGC, using current grading fees and live grade-adjusted prices. No more guessing.
Want list, alongside what you already own
Mark books as Want List to track hunts. When a wanted book appears in your scan flow, Stash flags it instantly.
Sell when you're ready, on any platform
If you decide to sell, the Seller tier publishes to 12 marketplaces. No vendor lock-in. You're free to list anywhere or nowhere.
The marketplaces that matter for you.
Free
Most personal collectors fit inside the Free tier's 500-comic limit. Upgrade to Collector ($5/mo) when you grow past that.

Stash Management. Free for up to 500 comics, with mobile scanning, live market values across all 7 grades, and AI slab and press analysis. When you're ready to sell, the Seller tier publishes across 12 marketplaces.
Is the free tier really free?+
Yes. Up to 500 comics, forever, no credit card. You get the iOS scanner, web dashboard, full sync, and CSV export.
Do I need to sell to use Stash?+
No. Many collectors use Stash purely for cataloging and valuations. Marketplace publishing is optional, move up to the Seller tier if and when you want to sell.
How does the slab calculator help me?+
When you scan a book, Stash compares its raw value against the grade-uplifted value at each CGC tier, subtracts current grading fees, and tells you whether grading would net you money. Useful for deciding what to ship to CGC.
