How Our Values Work

The trade value represents what an item is worth in the Sailor Piece trading economy. Unlike other sites that only show tier lists, our values reflect actual trading activity — what players are willing to give up to get an item.

Values are determined by community voting. Logged-in users (Level 2+) can vote on what they think items are worth. Votes accumulate over 72 hours, and our algorithm calculates a weighted median — giving more influence to experienced, active community members.

This means values can't be easily manipulated by a single person. It takes consistent community consensus to move a value.

Demand (1-5) measures how actively players are seeking an item — not how powerful it is. This is a critical distinction that most sites miss.

A combat-strong item might have low demand if it's untradeable or everyone already has it. A weaker item might have high demand if it's needed for crafting or is rare enough that collectors want it.

We calculate demand using real-money marketplace data. When real players spend real money to buy an item, that's the strongest possible signal of genuine demand. We monitor marketplace listing volumes and seller activity to determine which items players actually want.

We're one of the only Sailor Piece resources that tracks trading demand separately from combat tier rankings.

Some items show a USD market price. This is sourced from real-money trading marketplaces where players buy and sell Sailor Piece items for real currency.

The market price serves as an external reality check on community values. If the community values an item at 100K but people are paying $15 real money for it, that tells us something important about its true worth.

We don't endorse or facilitate real-money trading. Market prices are shown for informational purposes only, to help you understand the broader trading landscape.

Tier (S+, S, A, B, C, D) ranks items by combat effectiveness — damage output, utility, and how they perform in PvP and PvE.

Tier rankings are sourced from community guides and updated when game patches change the meta. A high tier doesn't always mean high trade value — and vice versa.

Not everything in Sailor Piece can be traded. Swords cannot be traded between players in-game — they must be crafted or purchased individually.

We still list swords with their stats, tier rankings, and crafting costs because they're a major part of the game. But their "value" represents crafting investment, not trade worth.
