Ditch the spreadsheet.
Numikeep keeps track of every coin you own — what you paid, what it's worth today, and where it's kept. Add a coin in a few taps. Watch the set fill in. See what the whole thing is worth without doing any of the maths.
iPhone, Android and the web. Free — no trial, no tier, no card.
Private by default. Your collection is yours, and never for sale.











Why we built it
You already have a list somewhere. It's out of date.
A spreadsheet, a notebook, or a shoebox of dealer invoices. It worked fine until the collection got big. Then the values went stale, updating it stopped being worth an evening, and now you are not entirely sure the list matches what is in the safe.
Nobody got into coins for the record-keeping. You got into it for the searching, and the moment a date you have been chasing for two years turns up in a junk box at a show. Numikeep does the remembering so you can get back to that.
The spreadsheet
- You type the values in yourself
- They go stale the moment you save it
- It lives on one computer, at home
- Adding a coin means opening a laptop
- Nobody else could make sense of it
Numikeep
- Values come from the price guide, not from you
- The total is current every time you open it
- It is on your phone, at the show, in your hand
- Adding a coin takes a few taps at the safe
- It reads like a proper catalogue of your collection












What it does
Quick to add. Good to look at. Yours alone.
Fast intake
Add a piece in a few taps, standing at the safe with the coin in your hand. Slabbed or raw — grading service, certification number and CAC status if it has them, and what you paid, when. No forms that punish you for having a big collection, and nothing you are forced to fill in.
Values you can check
Current CPG retail from Greysheet, matched to grade and CAC tier. When we can't price something we say so, instead of quietly leaving it out of your total — a number you can't trust is worse than no number.
Where everything is
Home safe, safe deposit box, out with a dealer on consignment. If you split a collection across three places — and most people eventually do — this is the part you'll use most. And it stays yours alone: where you keep your coins is never shown to a dealer, an auction house, or us when you sell.
Find anything instantly
Search and sort by series, date, grade or value. Settle the “do I already have this one?” question at the table, before you buy the same date twice.
Your collection, today
$84,320
214 coins · 198 priced · updated this morning
No sums, no VLOOKUP, no tab called values_FINAL_v3. Open the app and the number is there, worked out from the current price guide and the grade of each coin you entered.
And when we cannot price something, we say so and leave it out of the total — 198 of 214 above. A number you cannot trust is worse than no number.
The unglamorous part
Every collector knows a guy.
If you collect Civil War tokens, you know that Steve Hayden is who you consign them to. If you collect Bust halves or world gold or Carson City dollars, you know your own version of that name — the dealer, the auction house, the one specialist who will actually get the price. That knowledge took years to pick up, and right now it exists in exactly one place: your head.
Coins outlive us. Yours are valuable, and they have been a good investment — which is precisely why it matters that they end up in the right hands rather than at whichever counter is closest and open on a Tuesday. A collection built over thirty years can be undone in one afternoon, and usually is, because the person carrying it in has no idea what they are holding or who to ask.
So Numikeep asks you one question, coin by coin or series by series, in your own words: where should this go if I'm not the one selling it?
- Consign the Civil War tokens to Steve Hayden — nobody else knows this stuff.
- Do not break up the Bust half set. It's worth more whole.
- The 1909-S VDB was Dad's. Sarah gets it, whatever it's worth.
- Anything gold — get two offers before you take one.
Then print an access card and keep it with your will or in your safe. Whoever needs it one day uses it to start a 30-day countdown; we email you every day of it, and unless you tap Stop, they get the whole picture: every piece, what you paid, what it's worth now, where it's kept, and your instructions for each one. Read-only.

You'll set it up once and hopefully never think about it again. And yes — if one of those notes says “ask Snowpack,” we'd be glad. But a note that sends your coins somewhere else entirely is worth just as much to us, because the point is that they sell well, not that they sell to us.
Privacy
Your collection is yours.
A list of what you own and which safe it is in is not something to be careless with. It is stored encrypted, it travels over an encrypted connection, and it is never sold, shared, rented or shown to anyone else. There is no advertising in Numikeep and there never will be.
Who can see it, in plain terms:
You
Whenever you like
On your phone, your computer, or the web. It is your collection.
Snowpack staff
To run it, or to help you
Getting you back into your account, or fixing something that broke. Not to browse.
Anyone else
Never
Not advertisers, not data brokers, not other collectors. It is not for sale at any price.
Encrypted, going and sitting still
Your collection travels over an encrypted connection and is stored on encrypted disks. Ordinary, boring, and the same protection your bank statements get.
Nobody here browses collections
Reaching a collection takes a deliberate, recorded action, done to fix something or to get you back in. It is not a screen anyone can idly open, and it is never used to decide what to offer you.
Never sold, to anybody
No advertisers, no data brokers, no “partners”. We are a coin dealer that makes money selling coins, not a company that makes money knowing things about you.
Four ways back in, so one bad day can’t lock you out.
Forget a password, lose a phone, change your email — you can still get to your collection.
Your password
The ordinary way.
Your fingerprint or face
One touch, nothing to remember.
A link we email you
Works once, expires in fifteen minutes.
Your backup phrase
Six words, for the day the others fail.
Two promises from a coin dealer. We do not go looking through collections for coins worth buying, and we will never make you an offer on something you did not show us. Both are written into our terms of service, and you should hold us to them.
The price
Free. Here's how that works.
Numikeep is built by Snowpack Numismatics, a coin dealer. We're not selling you software and we're not selling your data — we make our money on coins, and a collector who trusts us is worth vastly more than a mailing list.
We make money if, one day, you decide to sell something and think of us first. Showing us a coin is a deliberate act, one coin at a time, and it puts that piece in front of a buyer here — which is different from it simply sitting in your collection. If you never sell us a thing, the app works exactly the same, forever. That's the whole arrangement.
Where you keep a coin never goes with it. When you show a coin to us, a dealer or an auction house, they see the coin — what it is, its grade, its certification and your photos. Never where it is stored, what you paid, or your own notes. Nobody should learn where your collection lives.

Questions
Straight answers.
Do I need to understand the security part?
No. You sign in with an email and a password, the same as anything else. Turn on your fingerprint if you want it, and save your backup phrase somewhere sensible. That is the whole of it.
What if I forget my password?
We email you a reset link, like any normal account. If your email has also gone, your backup phrase gets you in — and if all of that has failed, write to us and a person will help you prove who you are. Your collection should never be one lost password away from gone.
Is it really free, or free for now?
Free. There is no paid tier for your collection, valuations, location tracking or the legacy plan. If we ever build something genuinely specialist — dealer tools, market hunting — that might be paid, and what you already use won't change.
How long does it take to enter a collection?
A few seconds per coin once you're going. There's no bulk import yet — it's on the list, and if you have a spreadsheet already, tell us what shape it's in and we'll build for that.
What happens if Numikeep shuts down?
You can export the whole thing to a file whenever you like — including back to a spreadsheet, if that is where you want it. If we ever wind the service down you get at least 90 days’ notice and export keeps working the entire time. Your coins are in your safe either way; what is at stake is the record, and you can always take a copy of it.
Where do the values come from?
CPG retail pricing from Greysheet, matched on grade and CAC tier. We show when a quote was last updated and flag anything stale, because a confident number from two years ago is how people get talked down on price.
Do I have to sell my coins to you?
No, and nothing in the app pushes you to. Showing us a coin is something you choose, one piece at a time, and you can take it back afterwards. Wherever you send a coin, its storage location stays private — it is never shared.
Can I use it on more than one device?
Yes, and there is nothing to set up. Sign in on your phone, your laptop, the web — it is the same collection, up to date on all of them. After the first sign-in each device can open with your face or your fingerprint, like everything else on your phone.
Can Snowpack see what I own?
A few people here can, and only to run the service or to help you — getting you back into your account, or fixing something that has gone wrong. Nobody browses collections for interest, it is never used to work out what to offer you, and it is never sold or shared. The privacy policy spells out exactly what we hold and who touches it.
Early access
It's being built now.
We'd rather ship something a collector can trust than something quick. Leave your email and we'll tell you the day it's ready — and we'll take your notes on what it's missing.
We use your address only for early access. No newsletter, no marketing list — one message when it ships.
