Coin Collection Inventory Log

A coin collection inventory app and log book that works offline, with no account and no camera trick.

You own coins worth more than you think, and right now you can't prove it. Spreadsheets, paper and memory fail the day you need to insure, sell or pass on the collection. Coin Collection Inventory Log is a searchable offline ledger that fits in your pocket and never needs a connection to do its job.

── A COIN COLLECTION INVENTORY, NOT A COIN IDENTIFIER ──

This is a manual coin collection log. It does not identify a coin from a photo, it does not look up any price guide, and it does not estimate market value. Every figure in the app is one you typed yourself. If you want a scanner, this is the wrong app, and we would rather tell you now than take your money.

── WHAT YOU CAN LOG ──

① Year and denomination, every coin in your collection, entered once
② Mint mark, an open text field, so any mark from any country fits
③ Condition, on an eight step scale from Poor to Proof
④ Value, the figure YOU enter: your own estimate, the price you paid, or an insurance note
⑤ Notes, provenance, seller, auction lot, whatever you want to remember
⑥ One photo per coin, from your gallery
⑦ Sets, to group a collection by country, by era or by series
⑧ Want list, for the coins you are still hunting
⑨ Search and filters, find any coin in seconds by country, year, denomination or mint mark

── COIN COLLECTION LOG BOOK, THE WAY A NUMISMATIST WRITES IT ──

A spreadsheet has no coin fields and no instant search when you stand at a table with 200 coins in front of you. This log book is built around what a numismatist writes down: condition first, mint mark second, value third.

── WHY OFFLINE MATTERS ──

Coin identifier apps need a camera and a server. At a coin show, an estate auction or a safe deposit box, you may have neither. The ledger itself works with no Wi-Fi, no mobile data and no account. Your coins, your photos and your notes stay on your device. Like most apps that show ads, this one declares network access, an advertising identifier and billing, used for ads and purchases, never for your collection.

── WHO THIS IS FOR ──

• Numismatists cataloguing a serious collection, from any country or period
• Weekend collectors building a first inventory before sending coins to be graded
• Heirs and executors who need to document a coin collection they inherited
• Dealers who want a fast pocket log

── WHAT PRO ADDS ──

The inventory is yours without paying: unlimited coins, every field, sets, want list, one photo per coin, and the CSV copy. Pro removes the ads and adds one thing more:

• The insurance dossier, a PDF of your whole collection, built offline on your device, ready to hand to an insurer, a notary or an heir. It states plainly that the values were entered by you and that no appraisal was performed.

Pro is a one time purchase that stays yours with no renewal, or a monthly subscription, or a weekly subscription with a 7 day trial during which ads keep showing. Subscriptions renew automatically until you cancel them in Google Play. There is also an option that removes the ads on their own, as a one time purchase.

── YOUR DATA ──

No account, no sign in, no cloud sync. Copy your whole collection as CSV to the clipboard whenever you want, with no payment.
