How to price-check items in GPO
Price-checking in Grand Piece Online is tricky because there's no official value list. Values shift weekly, and sometimes daily during events. Here's how to do it properly.
Step 1 — look up each item individually
Use our calculator or search by name or shortcut. Every value comes with:
- A point estimate (for example, 71,000)
- A confidence range (for example, 63K–79K)
- A confidence flag: high, medium, or low data (treat as a rough estimate)
- A demand label: terrible, low, normal, high, or amazing
If an item is flagged low data, don't use our number as your only source. Cross-check with the community.
Step 2 — calculate the full trade
Use the calculator. Add items to the "You" and "Them" sides. The verdict pill tells you win, fair, or lose:
- Win — you're receiving more value than you're giving.
- Fair — value ranges overlap (within roughly 8%).
- Lose — you're giving more than you receive.
Step 3 — cross-check community sources
Even with over a million trade messages, we can be wrong, especially for thin-trade exclusives (Marine Cap, Cool Shades, Marine Cape) that mostly trade via DM. Cross-check with:
- Pinned value lists in your trading Discord
- the Fandom wiki value tables
- Other community value sites
If two sources disagree by under 10%, trust ours. If they disagree by 30% or more, lean toward community consensus.
Step 4 — spot scam ratios
Our solver auto-rejects the obvious ones, but players still send scam offers:
- Cross-tier 1:1 — "1 PCC for 1 ASB" (Collectable for Legendary) is always a scam.
- Unpaired prestige — accepting a prestige item without its natural pair.
- Adds never shown — "and adds" only means something when it's specified. If they won't clarify, assume minimum adds.
- Urgency pressure — "fast trade" or "leaving in 5 min" is always a manipulation tactic.
