All moversAbout GPOValue
GPOValue is a free, community-run tool for Grand Piece Online (GPO) players. Use it to check whether a trade is worth accepting, browse current values for every tracked item, see which items are rising or falling in demand, and find trade-up ideas based on today's prices.
GPOValue is not the official Grand Piece Online values source, and it isn't affiliated with Grand Quest Games or Roblox Corporation. Values here are informational estimates kept current by hand by our own team, not automatically generated — treat them as a guide rather than a guarantee, and always double-check a trade yourself before accepting it in-game.
Values
What every item trades for, from most to least valuable. Tap a card for details, or use the buttons to drop it straight into a trade.

How the verdict works
Trade Check adds up everything you give and everything you get, then compares the two totals.
- Win: you get at least 5% more than you give.
- Fair: the totals are within 5% of each other.
- Lose: you get at least 5% less than you give.
On a losing trade it suggests items worth about the gap, so you know what to ask for.
Where the numbers come from
A value is an estimate of what an item usually trades for, on one shared scale. That lets you compare a fruit with a weapon, or three small items with one big one.
Values change with demand, game updates and events. Treat them as a guide, not a promise. Every change is logged on the Movers page, and charts fill in as values move.
Value versus demand
Value is what an item is worth. Demand is how quickly it sells. A high-value item in low demand can sit unsold for a long time, while a smaller item in high demand moves fast. Check both before you trade.
Using the trade window
Trade Check works like the real trade screen. Both sides start with empty + slots. Tap a slot to pick an item, or type a code such as PCC under a panel and press Enter. Each item shows its value, and the Item values panel adds everything up.
Tap a filled slot to change how many you have, move it to the other side, or remove it.
Posting a trade

Staying safe
- Re-check the offer. Look at both sides of the trade window again right before you accept.
- Never give first. "I'll pay you back" is a classic scam.
- Check the price yourself. If someone says an item is worth far more than the list, don't take their word for it.
- Skip strange links. Don't click links or download files from strangers offering trades.
- Slow down. A deal that must happen this second usually isn't in your favor.
Trading words
- WFL: win, fair or lose.
- Overpay: giving more value than you get, usually to land an item in high demand.
- Trade-up: swapping for something worth more, often in several steps.
- Demand: how many players want an item right now.

Our Discord bot
The bot answers price questions right in Discord. Use /value and pick an item, or just mention one: type its name, its code (like PCC) or its emoji and the bot replies with the value, rank, demand and even swaps.
Use /trade to check a whole trade, for example /trade give: 2x pcc get: pwe, pirb. Every reply links back to the item or trade on this site. Add the bot to your server
