Answers to common questions about gpovalues.com, Grand Piece Online trading, and how our math-driven value system works.
Every value on gpovalues.com is derived from observed Discord trade messages — about 1 million parsed trade offers across 7 community channels. We use a statistical solver (Dijkstra ratio chain + iterative weighted-median bundle re-valuation + two-window time decay) anchored at Mythical Fruit Chest = 10,000. Full method at /legal/methodology.
Exclusive-tier items (Marine Cap, Marine Cape, Cool Shades) mostly trade privately via DM or in Patreon-only channels — our public-channel parser can't see those. Community feel sits above our math-only number, which is why we flag these with 'LOW DATA' or widened confidence ranges.
Our pipeline runs daily. Price history snapshots capture each day; the short-window solver (12-hour half-life) responds to fresh market moves within hours for active items.
An item with fewer than 200 observed trades in the window gets the LOW DATA badge. Treat the listed value as a rough estimate rather than a precise price. Real value could swing ±30% day-to-day.
PCC stands for Prestige Candy Cane, a Collectable prestige-tier sword released during the 1st Anniversary event in 2024. See our full guide at /guide/what-is-pcc.
WFL = Win / Fair / Lose. It's the community shorthand for evaluating whether a trade is in your favor. Our calculator's center pill shows this automatically: green WIN means you're gaining value, yellow FAIR means the value ranges overlap, red LOSE means you're giving up more than you receive.
Every value is measured relative to Mythical Fruit Chest = 10,000 value points. So PCC at 2,000,000 means PCC is worth about 200 Mythical Fruit Chests.
Our solver learns the typical value of +Adds from paired trades that differ only by the presence of adds. Adds scale with trade tier: ~1,500 for low-tier trades, ~250,000 for prestige-tier trades.
We auto-drop pure 1:1 trades across two or more rarity tiers (Collectable for Rare, for example) unless compensating mods are specified. These are virtually always scam lowballs.
No. This is an UNOFFICIAL fan site, not affiliated with Grand Quest Games, Roblox Corporation, or the official GPO development team. All item names and artwork remain property of their respective owners.
We're preparing a free public API (no keys required for basic reads). If you want early access or a bulk JSON dump, message [email protected].
Join our Discord and flag the item; we'll show you the specific trades producing the number. If the community consensus strongly disagrees with ours, we investigate parsing errors or missing channels.

Different sites use different anchor units. We use MFC = 10,000; some sites use MFC = 4,000 (divide ours by 2.5 to compare). Methodology also differs — we're math-only while most are hand-curated.
Items with very low drop rates (Halloween-era PWE at 0.000005%, Anniversary prestige items) tend to rise as supply depletes. Items re-released or buffed in an update often fall. Check /guide/gpo-trading-guide.
