About OneZeroTwo

A Pokemon card value lookup, built by someone who sells cards at shows.

What it is

OneZeroTwo answers one question first: what is this card worth right now. You type a card name, add the card number if you have it, and you get the value for the grade you care about, the sold comps that number was worked out from, and an honest read on whether the card is moving up, sitting flat, or sliding.

It is not a marketplace. Nothing is for sale here, there is nothing to bid on, and no listing is being pushed at you. It is a pricing and record-keeping tool that sits alongside wherever you already buy and sell.

What you can do with it

Card search and the current value are free for everyone, signed in or not. Daily photo scans and collection and watchlist sizes rise with the plan; the tools marked Pro are Pro only.

Look up a card. Graded values for PSA, CGC and BGS with PSA as the primary grade, plus raw. The sold comps behind the number are shown, so you can look at the tape instead of taking a figure on faith.
Read the trend. A trailing trend, a 3-month projection drawn with an uncertainty band, and a Trend Score that shows its own weighted breakdown rather than hiding inside a black box.
Keep a collection. Add the cards you own, see what the whole portfolio is worth, and get an action read on each one instead of a wall of numbers.
Watch cards you do not own yet. A watchlist, with alerts when something you are tracking moves.
Weigh up a trade (Pro). Trade Mode puts both sides of a proposed swap on the same scale and says who is ahead and by how much.
Keep a sales ledger (Pro). Record what you paid and what you sold for, and export the year to a spreadsheet when tax time arrives.
Scan a slab. Point a photo at a graded card label and the scanner reads the label text, then hands you a link to check the certificate on the grading company's own site. Every plan can scan; the daily allowance grows with the plan.

Who makes it

One person: a working card dealer who runs a table at weekend shows. Every feature here exists because a real table needed it. Pricing a card while somebody stands in front of you waiting. Valuing a pile of trade bait without doing arithmetic in your head across ten cards. Knowing, at tax time, what you actually paid for the things you sold that year. Nothing was built because it demos well.

The honesty stance

Three rules the whole app is built around, and they are enforced in code, not just in intent.

A price is never invented. If a source has no data for a card, the app says it has no data. It does not fill the gap with a plausible looking number, and it does not quietly substitute a different card's price.
Anything estimated is labeled as an estimate. The trend, the projection and the Trend Score are heuristics. Where an accuracy figure exists it comes from a backtest you can rerun, and the two figures that exist are never mixed up with each other.
Caveats sit next to the number, not in a footnote. PriceCharting's graded history is mostly PSA, so when CGC or BGS data is thin the app shows the PSA figure as a proxy and says so on the spot. A card with too few recent sales is marked illiquid and its confidence is forced down.

What it does not do

It does not give financial or investment advice. Cards are not a savings account.
It does not store card photos. A scanned photo is processed in memory and dropped, never written to disk or to the database.
It does not sell or resell your data, and there are no analytics or advertising trackers on the site.
It does not report eBay sold prices. The eBay panel shows active listings, which are asking prices, and those are kept out of the sold-comp analysis on purpose.
