Features / A card for every coin

The coin card is the heart of OutOfDark. In one place you get photos, details, certification, catalog references, the acquired price, current value, grade, notes and historical context. No scattered spreadsheets and drawers.

Everything about a coin in one place

Identity, physical details, fineness, rarity, catalog references, acquired price, today's value, grade and historical context – one catalog card for your insurer, your heirs, your own research, or just for the joy of it. Nothing gets lost in notes and spreadsheets.

Detailed parameters for every coin

For every coin you fill in exactly what you need – the mint, rarity, engraver, minted year, mintage, catalog number, grade and certificate. Every piece is documented down to the detail, just the way a numismatist appreciates.

We'll find the missing details

Don't know your coin's weight, diameter, mint or engraver? With one click we look it up in the worldwide Numista catalog and offer to fill in the gaps – weight, diameter, material, mint, mintage and international catalog references.

The story of every coin

For each coin you keep a description of its motif and the historical context of the era and ruler. Add it yourself, or let AI Mincmistr gladly look it up and write it for you. Every piece becomes a little piece of history, not just a row in a spreadsheet.

Smart helpers as you type

We build the coin's name from the fields you fill in, individual fields suggest values you've already used, and dates pre-fill automatically when needed. Adding a coin is a matter of moments, not a long slog through a form.

Photos that are a joy to work with

OutOfDark automatically straightens, crops, resizes and saves your uploaded photos in a space-saving format. Snapshots from your phone turn into a tidy gallery of the obverse, reverse and close-ups – with no manual editing in an external tool.

Mark up details right on the photo

Frame and label damage, mint marks or rarity signs right on the photo. It helps you keep the coin's important details together – for yourself and for a potential buyer.

Certification and a verification QR code

For certified pieces (NGC, PCGS, CAC, ANACS, ICG) you enter the number and the Sheldon grade, and the verification link and QR code are created for you. Anyone who gets the coin card can verify authenticity with a single scan from their phone.

Compare coins side by side

Line up the coins you're interested in and compare their details, grade and prices at a single glance. Handy when deciding which one to sell, or just for study. And you can save the whole comparison as a PDF or print it.

Keep your purchase history

For each coin you record when, for how much and from whom you bought it, plus a link to the original listing. You update the current value over time and OutOfDark remembers how it evolves – so you can watch your collection grow.

Watch the value grow

We pull gold and silver prices every day. For your bullion coins you switch on recalculation against the live metal price, and their value updates itself – no manual rewriting or math. So you always see what your collection is really holding.

History for every coin

Every coin has its own logbook – when the grade changed, how the value evolved and who edited what. Nothing gets lost, and you can revisit what happened to any one piece over time.

Private notes just for you

Add internal notes to a coin that only you can see. When you share the coin by link, your private notes show up nowhere – not even in the page source. Your behind-the-scenes stays yours.

Print a catalog sheet

From the coin card you print a neat catalog sheet with every detail, the photos and the certificate in a single click. Great as proof for your insurer, for your heirs, or just for your own binder beside the collection.

Display labels

For your personal collection, an exhibition or a coin fair, print tidy display labels with the detailed parameters and grade. No more writing anything out by hand – just cut them out and slip one under each coin in its tray. Your collection ends up looking professional.

Share a coin with whoever you like

Want to show someone one particular coin? Create a link to it and send it to anyone – a prospective buyer or a fellow collector. You don't have to share sensitive price details, and you can revoke the link with one click anytime.

Your collection always in your pocket

The app is in your pocket whenever you need it – all it takes is your phone. Easily check your collection, look something up or add a new piece on the spot, whether you're at a coin fair, an auction or anywhere on the road.
