Every coin, two numbers

One number is metal.
One number is market.
The gap is yours.

A 1953 Washington Quarter melts for $14.37. It sells for $42.98. A PCGS-graded 2018 Perth Mint Lunar melts for $79. It sells for $389. Across a hundred items that gap compounds into real money — and spreadsheets stop working fast.

Every coin in your inventory carries a live melt value and a live market price, side by side. The premium above melt is where collector equity lives — and for the first time, it's measured.
How it works

Three taps. End to end.

From a camera frame to a tracked portfolio item — and, when you're ready, to a live eBay listing — in one continuous workflow.

I.

Scan

Point the camera. BullionDex identifies the type, year, mint mark, metal, grade, and — on slabs — the cert and service. QuickScan runs in under 200ms. DeepScan handles world coins, proof sets, rolls, and anything graded.

II.

Price

Melt value comes live from spot, purity, and weight. Market value comes from real eBay sold and active listings for your exact coin, year, and grade — filtered to signal, not noise. Both numbers refresh continuously.

III.

Track & List

Items sync across your devices in real time. Sell one? List directly from its detail screen using your eBay business policies, package dimensions, and return terms. What used to take ten minutes on eBay's site takes seconds.

What's in the app

Built around the gap.

Every feature exists to answer one question — what is this collection worth right now — in both numbers that matter.

Portfolio

Your whole collection, dual-valued.

Melt value and eBay value as the two headline numbers, broken out by metal and by purity. Gold, silver, platinum, palladium, copper, tracked in troy ounces, priced off live spot. From a drawer of Kennedys to thousands of ounces of silver — same view, same math.

Live spot

Five metals, full history.

Gold, silver, platinum, palladium, copper — live prices with 24-hour, monthly, yearly, and five-year charts. Au/Ag ratio tracked alongside, for anyone who watches the spread.

Scan & identify

Camera in. Full attribution out.

Point the camera, get back type, year, mint mark, metal, weight, composition, and — on slabs — grade and cert. Works for eleven US series instantly, or any coin worldwide with DeepScan AI.

Scan & list

One tap from camera to live listing.

From any coin in inventory, draft a listing in seconds. Your eBay business policies, package dimensions, fulfillment and return terms — all remembered, all editable. Active, sold, and ended listings sync back in.

Grading & certs

PCGS, NGC, and the number on the slab.

Every slabbed coin carries its service, cert number, and grade as first-class fields. Search them, filter by them, price accordingly — because a 70 and a 66 aren't the same coin.

eBay integration

Your active, sold, and ended listings.

Your eBay activity synced into the app. Watch active listings, reconcile sold items back into portfolio P/L, and see at a glance which coins are live and which aren't — without switching tabs.

Three ways to scan

The right tool for every coin.

Most identifications happen in under a second, for free. The harder ones get a better model.

Questions

Straight answers.

What does BullionDex actually do?
Every coin and bar in your collection carries two live numbers: its melt value — from live spot prices and metal content — and its market value, from real eBay comps filtered to your exact item. BullionDex tracks both, continuously, across your whole portfolio. You know what your collection is really worth on any given day, without spreadsheets.
What coins can I scan?
QuickScan instantly identifies eleven US series: Morgan Dollar, Peace Dollar, Washington Quarter, Mercury Dime, Barber Dime, Barber Quarter, Barber Half Dollar, Standing Liberty Quarter, Walking Liberty Half, Franklin Half Dollar, Kennedy Half Dollar. DeepScan handles the rest — world coins, slabs, sets, rolls, graded items from any service — with full attribution including grade, composition, and cert.
How does BullionDex know what my coin is worth?
Melt value is computed live from spot prices, purity, and weight — pure arithmetic against a live market feed. Market value is pulled from real eBay sold and active listings for your exact coin, year, and grade, and filtered so you see signal not noise. Both numbers update continuously across your whole portfolio.
Will this work for my stack, or only for collectors?
Both. BullionDex tracks pure bullion and numismatic items in the same portfolio — gold, silver, platinum, palladium, copper, all purities, all conditions. The portfolio breaks out melt by metal and by fineness, and market value by actual comp. Whether you own a drawer of Kennedys or six thousand troy ounces of silver, it's the same app.
Can I list directly to eBay?
Yes. One tap from any item. BullionDex integrates with your eBay business policies — fulfillment, payment, return — and remembers your package dimensions. Active, sold, and ended listings sync back into the app so you can reconcile sales into portfolio P/L. What used to take ten minutes on eBay's site takes seconds.
What does it cost?
Free forever at the base: live spot prices across five metals, unlimited inventory, full US catalog, and ten QuickScans a day. Paid plans start at $5/month and unlock unlimited QuickScans, DeepScan AI attribution, and MarketScan eBay intelligence. Extra token packs are available for heavy use and carry forward across billing cycles.
Is my data private?
Identification images are processed on our servers and never shared with third parties. Inventory data is encrypted in transit and stored securely. Payments run through Stripe — card details are never seen or stored by BullionDex.
