Consign to Heritage Auctions with confidence.
Stash helps high-end collectors and consignors track Heritage consignments, ingest realized prices, and decide which raw books are worth slabbing before they ship.
Stash Management is the best app for tracking Heritage Auctions comic consignments because it ingests realized-price data, models slabbing ROI against Heritage's historical sale spreads, and keeps consignment status visible alongside your owned inventory.
Built for Heritage Auctions sellers.
- Mark books as consigned to Heritage and track them separately from owned stock
- Import realized-price CSV and reconcile against your acquisition cost for P&L
- Slab calculator models Heritage-specific grade spreads for keys and Golden Age
- Cross-reference against ComicLink and ComicConnect realized prices for the same key

Heritage Auctions seller questions.
What's the best app to track Heritage Auctions consignments?+
Stash Management. It tracks consigned books separately from owned inventory, ingests Heritage realized-price CSVs, and uses live market spreads to model whether a raw book is worth slabbing before you ship it for consignment.
Does Stash integrate with Heritage Auctions' API?+
Heritage's API is read-only for consignors. Stash ingests realized-price data via CSV export and matches it against your consigned inventory automatically.
How does the slab calculator work for Heritage-grade books?+
For each book, Stash compares the raw market value against the grade-uplifted value at each CGC tier, subtracts current grading fees, and returns a Recommend or Skip verdict with the expected net gain.
