Coin Stacker doesn't sell coins. It's your price check wherever you buy them: eBay, WhatNot, shows and dealers.
Collecting is fun. Guessing isn't.
Coin Stacker replaces the spreadsheet, the camera roll and the price-lookup tabs with one app that knows your collection and the market.
- Your spreadsheet was accurate in March.
- You have five tabs open to price one coin.
- That app said your quarter was worth $6,000.
- You bought a coin at the show, got home and found you already had it.
- You think you're close on your Morgans. You don't know which dates you're missing.
Every slab, raw coin and ounce, valued.
Add coins by snapping a photo, typing in a cert number, uploading a spreadsheet or importing your WhatNot orders. Coin Stacker reads the coin and the slab label, fills in the details, and prices every piece from real market data. It refreshes every night.
- Every field a serious collector tracks: grader, grade, cert, CAC, variety, pedigree, cost and source.
- Search, filter and find any coin in seconds.
- Know which box or safe every coin is in.
- See your collection's value today, and how it has moved over time.
A second opinion before every bid.
At a show table or during a live stream, point your camera at the coin. In seconds you'll know what it is, what it really sells for, and whether the asking price is fair. You'll also see whether you already own it, and whether it fills a gap in a set you're building.
- Prices from eBay listings and comps, the PCGS price guide and Greysheet dealer wholesale, side by side.
- Strict matching, so an Early Releases slab isn't priced like a plain one.
- A clear verdict on the price you're being asked.
- Key dates and semi-keys flagged before you pass on them.
Prices from the sources dealers use, not a guess.
We don't sell coins, so we have no reason to inflate a price. Most coin apps show one number and hope you believe it. Coin Stacker shows its work: market comps, the PCGS guide, dealer wholesale bid and ask, and melt value from live spot prices. You see what a coin sells for, what a dealer would pay you, and what the metal alone is worth.

Questions
Do you sell coins?
No. Coin Stacker is a tracking and pricing app. You buy wherever you like, and we help you know what you have and what a fair price is.
Where do the prices come from?
eBay listings and comps, the PCGS price guide, Greysheet/CDN dealer wholesale, Numista for world coins, and live spot prices for melt. They're shown side by side so you can judge for yourself.
Is it accurate at identifying coins?
It reads both the coin and the slab label, and you confirm every coin before it's saved. If it gets one wrong, your correction fixes that coin's next scan.
Does it work with graded coins?
Yes: PCGS, NGC, ANACS and ICG slabs, including cert numbers, CAC stickers and special labels.
Can I import my spreadsheet?
Yes. Upload CSV or Excel, check the suggested column mapping, and import. Rows with problems are reported, not silently dropped.
Is my collection private?
Yes. Every record is locked to your account, and photos are served through expiring private links.
Is there an Android app?
Not yet. Coin Stacker works in any browser, including on Android phones.
Can I cancel any time?
Yes, from your billing settings. You keep access until the end of the period you paid for.
