AI-Powered Identification

Identify any coin in seconds

Upload a photo and StackerKit's AI identifies the coin, estimates the grade, and gives you a value range — the same criteria a numismatist uses.

Photo Identification

Snap a photo of any coin. AI returns the denomination, date, mint mark, and variety in seconds.

Grade Estimation

AI evaluates strike, luster, and surface preservation to estimate a Sheldon-scale grade.

Slab Photo Reading

Point your camera at a PCGS, NGC, CACG, or ANACS slab — AI extracts the cert number and looks it up automatically.

Auto-Fill Details

AI fills in denomination, composition, weight, diameter, and designer — so you don't have to type a thing.

Certified Coin Lookup

Three major grading services, built in

Enter a cert number — or scan the slab — and get the full details instantly. Grade, variety, population data, price guide values, and a virtual slab display. ANACS support via AI photo extraction.

PCGS Lookup

Live API integration. Cert number returns grade, variety, price guide value, population, and imagery.

NGC Lookup

Full NGC cert data including grade, designation, variety, and population report.

CACG Lookup

CAC Grading cert lookup with full details, plus CAC sticker verification for PCGS and NGC coins.

ANACS via AI Photo

ANACS doesn't offer a public API. Photograph an ANACS slab and AI extracts all fields — cert number, grade, denomination, date, and more.

Bequests & Beneficiaries

Assign coins and collections to named beneficiaries. Invite family members to view their designations.

Smart Bid Runways

Color-coded visualization shows exactly where every lot stands relative to fair market value and melt floor. Suggested bids calculated from analysis confidence, your target margin, and platform fees.

Outbid Alerts

Browser notifications the instant someone outbids you. Full bid history charts show exactly who's bidding and when.

AI does the heavy lifting.
StackerKit's AI features are designed to assist your research — not replace your expertise. Coin identification, grade estimation, and cert extraction are powered by modern vision models trained on numismatic data. Always verify against PCGS, NGC, or a qualified numismatist before making buying or selling decisions.*
