Organize a
stamp collection

A collection is easier to enjoy, insure and sell when you know what is in it. Here is a simple order that works for an inherited box as well as for a growing album.

Step by step

  1. Sort by issuer

    Make one pile per country or postal administration. If you cannot read an inscription, look it up by the words on the stamp in our issuer directory.

  2. Then by period

    Within each issuer, sort by era or by reign: classics, inter-war, post-war, modern. The currency on the stamp is a quick clue.

  3. Separate duplicates

    Keep the best copy for the collection and put the rest aside for swaps.

  4. Note the condition

    Mint never hinged, mint hinged or used. Write it down: it matters more for value than almost anything else.

  5. Add catalog numbers

    Scott, Michel, Stanley Gibbons or your local catalog. Numbers make a collection searchable and comparable with price lists.

  6. Store it safely

    Use a stockbook or a hingeless album, handle stamps with tongs, and keep them away from sunlight, damp and adhesive tape.

  7. Keep a record

    A list or photos of every page protect you against loss and make a later sale or insurance claim far easier.

Album or app?

They do different jobs. The album keeps the stamps; the app keeps what you know about them.

Your collection in the app

Every stamp you identify can be saved with one tap: photo, issuer, year, catalog numbers and rarity score. Search the list by name, open any stamp to see its full entry, and delete what you no longer need. From app version 2.0 the collection is also kept on our server, so it comes back when you reinstall the app on the same iPhone.

Questions about organizing

By issuer first, then by period or catalog number. Thematic collectors sort by topic instead, such as birds or ships, and note the issuer on each page.

A stockbook is quick and flexible for sorting and duplicates. A printed or hingeless album suits a finished country collection. Many collectors use both.

Hinges leave a mark that lowers the value of mint stamps. Use clear mounts or a stockbook for mint stamps; hinges are acceptable for common used stamps.

Not yet. The app keeps your saved stamps with search and restores them after a reinstall on the same iPhone, but it has no export or sharing.
