Track Your Pokémon Card Collection

Every serious collector has built the spreadsheet. Card, set, paid, worth. It works for a month. Then the value column goes stale, the photos live somewhere else, the file forks between two devices, and one day the collection has outgrown the person maintaining it. The information you wanted lives on, wrong, which is worse than absent.

What you actually want from tracking is simple. What do I own, what did it cost, what is it worth today, and where is the proof if I ever sell. Getting those four answers without manual upkeep is the whole point of purpose-built tracking.

A tracked card is only as useful as what you record on it, and the habit that pays off is capturing everything at purchase time, while the receipt is still in front of you:

• What you paid, all-in: purchase price plus postage and fees, because that full figure is your real cost basis.
• When and where you bought it: the date drives holding periods for tax, and the seller matters if provenance ever comes up.
• Exactly which card: set, number and finish, so future you is not squinting at a corner trying to remember.
• Photos, front and back: your own record of condition on the day it arrived.
• Grade and cert for slabs: the cert number unlocks the PSA link and the automatic values.

None of this takes a minute per card at purchase time. Reconstructing it years later, across old emails and dead listings, takes far longer, and for tax records a reconstruction may not be good enough.

• Totals that mean something: collection value, total invested, and profit or loss, updated as values move rather than when you remember.
• Per-card history: what you paid, when, and how the value has moved since, charted on graded slabs.
• Best and worst performers: which cards actually carried the collection, and which purchases you would not repeat.
• Sold records by financial year: sale price, days held and profit per card, in the shape tax time expects.

Graded slabs keep their own values current from recent eBay sold prices, matched on the cert number. Raw cards you value yourself, whenever you check the market.

A spreadsheet comes across through CSV import. Map your columns once and every card arrives with its purchase price and value intact. Tidy the spreadsheet before you export it, because consistent set names and one row per card make the mapping clean, and ten minutes of tidying beats fixing cards one at a time afterwards. New cards go in by photo, with the details read off the image for you to confirm, or by hand when that is quicker. Most collections are fully across in an afternoon.

Tracking is free, with no card limit, and the collection backs up to the cloud as you go. Your data stays exportable to CSV at any time, so the door you came in through stays open.

Once the collection is on record, the record starts working for you. Selling on the marketplace starts from a card you have already photographed and priced. Purchase invoices and sold history become your tax paper trail instead of a reconstruction job. And insurance conversations go better when you can hand over an itemised list with values rather than a guess.
