StackerKit is a suite of AI-powered tools built for coin collectors, bullion stackers, and investors — to catalog, track, value, and plan the generational transfer of what you've built.
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.
Snap a photo of any coin. AI returns the denomination, date, mint mark, and variety in seconds.
AI evaluates strike, luster, and surface preservation to estimate a Sheldon-scale grade.
Point your camera at a PCGS, NGC, CACG, or ANACS slab — AI extracts the cert number and looks it up automatically.
AI fills in denomination, composition, weight, diameter, and designer — so you don't have to type a thing.
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.
Live API integration. Cert number returns grade, variety, price guide value, population, and imagery.
Full NGC cert data including grade, designation, variety, and population report.
CAC Grading cert lookup with full details, plus CAC sticker verification for PCGS and NGC coins.
ANACS doesn't offer a public API. Photograph an ANACS slab and AI extracts all fields — cert number, grade, denomination, date, and more.
Live spot prices for gold, silver, platinum, and palladium. Automatic melt value calculations. Portfolio charts that show how your collection grows over time.
Gold, silver, platinum, and palladium prices updated throughout the day. Visible on your dashboard at all times.
Automatic melt value from composition, weight, and purity. Multi-metal support for coins with complex alloys.
Daily snapshots of your total collection value. Charts for 30-day, 90-day, and all-time views.
See what you paid vs. current value for every coin. Know exactly where you stand on each piece.
Print QR code stickers for every coin, tube, roll, and storage location. Scan a sticker to jump straight to the item. Know exactly where everything lives.
Print Avery-compatible labels for every item. Round stickers for coins, rectangular for containers and storage.
Built-in camera scanner. Scan any sticker to instantly pull up the item, container, or location.
Log sealed rolls, tubes, bags, and boxes. Track contents by line item or link individual coins inside.
Location, rack, and bin hierarchy. Full move history. Optional — use it only if you want it.
Don't leave your family guessing. Assign specific items to specific people, simulate the distribution, and generate the documents your attorney needs — all in one place.
Assign coins and collections to named beneficiaries. Invite family members to view their designations.
Preview exactly who gets what. Simulation mode generates a watermarked PDF so nothing is final until you decide.
Generate a Schedule of Personal Property, inventory report, and distribution documents ready for your estate attorney.
A checklist that tracks what you've completed — legal documents, beneficiaries, bequests, and survivor instructions.
Track multiple auctions simultaneously, get AI-powered valuations on every lot, and never miss a bid — all from one dashboard. Built for serious collectors and bullion investors.
Monitor auctions across Bunting, HiBid, and more from a single dashboard. Every lot, every bid, every change in real time. Heritage, Stack's Bowers, and GreatCollections coming next.
Every lot runs through a pipeline — from instant algorithmic pricing to deep photo-by-photo gallery review. Know what a coin is actually worth before you bid.
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.
