GPO Values vs the Watashi Ruby Value List: How They Differ

If you search for Grand Piece Online values you will run into two sources that often disagree: the Watashi Ruby GPO value list, a long-running community list run through Discord, and this site, which solves values from logged trades. Neither is a copy of the other, and the disagreements are not random. This page explains what each one is, how each arrives at a number, why they diverge, and how to use the two together before a trade.

What the Watashi Ruby GPO value list is

The Watashi Ruby list is a community-maintained GPO value list distributed through its Discord server, discord.gg/gpovaluelist, named "GPO VALUE LIST by Watashi Ruby". Discord's public invite data reported 133,464 members and 26,405 online when we checked on September 6, 2026. Values there are set and updated by the server's team and published as tiers and figures inside the server, alongside channels for asking whether a trade is a win or a loss. It has been around for a long time and a large share of traders quote it, which is exactly why it is worth understanding how it differs from a data-driven list. We do not reproduce its values here; join the server to read them at the source.

What gpovalues.com is

gpovalues.com is a value list solved from real trades. We log completed and offered trades from public Discord trading channels, currently 173,992 logged trades, and solve for the set of item values that best explains what people actually gave up to get each item. The solve re-runs every hour, so a shift in the market shows up on the item page within the hour rather than when someone gets round to editing a list. Each value carries a confidence badge (high, medium or low) that reflects how many recent trades stand behind it, and every item page shows the trades it was solved from. The method is written up in full on our methodology page and, in more formal terms, on the legal methodology page.

Why the two disagree

When the two lists show different numbers for the same item, it is usually one of four things, and none of them requires either list to be wrong.

• Consensus versus observation. A curated list records what its team agrees an item should be worth. A solved list records what it did trade for. In a stable market the two converge; when sentiment and behaviour split, they do not.
• Timing after game updates. A new update changes demand overnight. A hand-edited list moves when its staff decide to move it; a solved list moves as soon as enough post-update trades are logged. For a day or two after a patch, expect the gap to be at its widest, in either direction.
• Thin-traded items. Items that change hands a few times a month give a solver very little to work with, which is why those items carry a low confidence badge here. A consensus list can still state a firm number for them; ours will be honest that the number is uncertain.
• Sub-tiers versus numbers. Community lists often group items into tiers with a value attached to the tier. Solving per item produces a distinct number for every item, so two items that share a tier elsewhere can sit a few points apart here.

About the "inaccurate values" claim

The Watashi server's invite description says that this site's values are inaccurate. We are not going to argue about it; we would rather make it easy to check. Every number on this site is produced by a published method from trade data you can read yourself: the browse page lists every item with its trade count and confidence, the value changes page records every move the solver has made and when, and any item page, for example Leopard, shows the trades behind its value. If a value looks wrong to you, the evidence for it is one click away, and our Discord takes value suggestions with community voting.

Check for yourself: our most-traded items

These are the ten items with the most logged trades behind them on this site, which makes them the easiest to compare against any other list. Open the item page to read the trades each value was solved from.

Values on this table are re-solved hourly from 173,992 logged trades; the figures above are from the latest build.

Which to use when

Use both. Come here for what the market is doing right now, especially in the days after an update, and for the confidence badge that tells you how much to trust a number. Use the Watashi Ruby list for where community consensus sits, which matters because the person you are trading with may be quoting it. Our GPO trading tier list has a section comparing our solved tiers with the hand-curated official list, and the Win / Fair / Loss calculator prices both sides of a trade against our numbers so you can see the gap before you accept. When the two lists disagree by a wide margin, treat that as the range and negotiate inside it.

FAQ

› Is the Watashi Ruby value list the same as gpovalues.com?

No. They are separate projects run by different people. The Watashi Ruby list is a Discord community whose team sets and updates values by hand; gpovalues.com solves values from logged trades and republishes them hourly.

› Why does gpovalues.com show a different value for an item than the Watashi list?

Because the two measure different things. A consensus list records what its team agrees an item should be worth; this site records what people actually gave up to get it in observed trades. The gap is widest right after a game update and on items that rarely trade.

› Which GPO value list should I trust for a trade?

Use both. Check what the market is doing now on this site, check where community consensus sits on a curated list, and if they disagree by a wide margin treat that as the range and negotiate inside it.

Two value lists disagreeing is a reason to check both, and neither of them sells you anything. If a fixed price is more useful to you than an estimate, PetMart publishes what it charges. PetMart is our own shop — the same people run both sites, and we make money when you buy there. It does not move the values.
