What Hunters Seek
Whatever you collect, Grail Den speaks your language.
Your Arsenal
Every module in the Den, built for obsessive collectors who demand precision, speed, and an unfair advantage. Your Den dashboard, in-app messages, and the resources library tie them together.
Search globally. Find your next grail.
One search runs across all 14 eBay sites at once. Listing titles translate on demand into 8 languages, a Japanese or Korean query is translated to English before the search, every price is shown in your currency, and items most collectors never see come up.
Connect your eBay account from Hunt; you sign in on eBay’s own page.

Catalog every piece with photos, provenance chains, and condition grading. Track value over time. Generate insurance reports from your own replacement values. Know your collection's true worth, always.
Every item opens to its tabs: overview, photos, provenance, authentication, trades, valuation, insurance, and notes.

17,000+ signing events on record, refreshed daily from the convention circuit. Star a signer to see their upcoming signings on your Den. Hunter and up.
17,000+ signing events · Daily refreshTrack deals, partners, payments, and the ledger.
Track consignments and private sales end to end: the deal, the partners, the payments, and a ledger that actually closes. Proposals go out from the tracker and land as deals when they are accepted. Scholar tier.
Deals · Payments · Ledger · ProposalsKeep provenance with the collection.
Each piece records its COA provider and number, serial, provenance notes, appraiser and appraisal date, what you paid and what it would cost to replace. Export the whole collection as a CSV spreadsheet, or print the replacement-value report with each piece’s COA, serial, location and value, so the people who inherit it know what they have.

Pro features that give you an unfair advantage in the hunt.
Submit a photo or eBay link. A working authenticator with deep experience in entertainment autographs examines the signature against signer exemplars on file, weighs era and signing context, and issues a documented opinion.
Quick opinions by Screen Grade authenticators, $9 per item.
Learn moreNot all sold comps are equal. Values anchored to the median of real sold comps, not asking prices.
Search more than 200,000 real sold listings for pieces like yours.
Your number sits on the median of what sold rather than the average, so one overpriced or lowball sale typically moves it less.
That gives you a number you can trust before you buy or sell.
Bring your collection in from a CSV spreadsheet, preview it first, and undo an import in one step. Hours become minutes.
Any spreadsheet saved as a CSV works; only a title column is required, and category, condition, dates, prices, location and notes come along if you have them.
Before anything is saved, a preview marks every row that has a title: will import, already in your collection, or needs a fix, with the reason. A row with no title is left out.
Clean rows import; rows that need a fix are skipped, never guessed. A file can hold up to 500 rows, so split a longer one first.
Changed your mind? One click undoes the whole import, for 24 hours.
