The prices in this hobby are wrong. We can show you why.

Riplytics started with a card that has five different prices and one name.

In One Piece’s OP13 set, Monkey.D.Luffy is card number 118. So is Monkey.D.Luffy. And so is Monkey.D.Luffy. There are five of them — the base card, the Parallel, the Wanted Poster, the Manga Rare, and the Red Manga Rare. Every single one is stamped Secret Rare, #OP13-118. Same number. Same printed rarity.

A seven-hundred-fold spread, inside one rarity label. Portgas.D.Ace runs $1.73 to $10,000 on the same card number.

Now consider what an “average sold price” for OP13-118 actually means. It is arithmetic performed on a seventeen-dollar card and a twelve-thousand-dollar card. It is not a price. It is a number with a dollar sign in front of it.

And it gets worse than a bad average. If a Red Manga sells one month and none sells the next, the “price” collapses ninety percent and a chart somewhere reports the card crashing. Nothing happened. The card didn’t move — the mixmoved. Every trend, every percentage, every “biggest mover” built on top of it inherits that noise, and somebody makes a decision with real money based on a chart that is describing an accounting artifact.

This is not a niche bug. It is how the entire category prices itself. And the collectors know — they had to invent a name for the Parallel, because it’s the card people buy thinking they got the manga. They call them Temu Mangas. That word exists because no data source would tell them the truth.

You cannot have an honest price without first knowing exactly which card you are looking at. Not the number. Not the rarity. The actual printing.

So that is what we built first: 34,712 cards across 348 sets — every main set, every promo, every event and tournament card, every starter deck — with 4,205 chase cards told apart from the base printings they share a number with. Alt arts. Manga rares. Parallels. Secret rares that run past the printed total.

It is the coordinate system. Everything true we ever say about a card has to hang off it.

There are no prices on this site yet, and we are not going to invent any. When they arrive, they will point at the sales underneath them. Here is everything we’re building, and everything we won’t fake.

Riplytics is built by John Gray, founder and CEO — and, first, a collector. For the last two years I’ve spent most evenings on Whatnot talking to One Piece and Pokémon collectors. Hundreds of them. The same things keep coming up.

People pay well over retail just to get product. People rip packs chasing a card without knowing the odds, or that buying the single outright is usually cheaper. People can’t tell whether a raw card is worth grading. People buy a Parallel thinking it’s a Manga. And a lot of people who spend real money on this game have never actually played it, so they can’t tell a card that wins tournaments from a card that’s just beautiful — which matters enormously, because one of those crashes on a rotation and the other doesn’t.

None of that is a knowledge problem on their part. It’s a data problem, and nobody in this hobby has an incentive to fix it. The people who sell you sealed product benefit from you not knowing the odds. The people who publish the prices are owned by the people who take the fees.

So: no invented numbers, no estimated prices, no chart without sales behind it. Where we don’t know, we say unknown — and mean it.

If a card is mislabeled, a set is missing, a manga rare is filed as a parallel — tell us. The corrections are the product. Every one makes the catalog something a competitor starting today cannot reproduce.

And if you’re a tournament organizer, a grader, a marketplace, or anyone sitting on data that would make this better, I’d like to talk.
