# Coins and the Dynamic Market

Bronze, Silver and Gold Coins are OceaniaRO's second currency. Almost everything the Tidemark Company pays you is denominated in them, and the place to spend them is the **Dynamic Market** in Prontera.

### Gold Coin storage

Gold Coins (item 7929) can go into **Kafra storage** and **cart**. They still cannot be sold to NPC vendors, traded, mailed, or auctioned.

## The Dynamic Market

**Where:** Prontera, 155 / 183 — just north of the fountain.

The Market buys and sells a fixed list of crafting materials, consumables and upgrade materials. Prices are not fixed. They move with what the whole server has been doing that day.

- Every **5 purchases** of an item raise its price by 1 coin.
- Every **10 sell-backs** lower it by 1 coin.
- Price can never fall below half the base, or rise above three times it.
- Everything resets at **midnight**.

Selling back pays **50% of the current buy price**, and pushes that item down for everyone — so a server that farms Oridecon hard makes Oridecon cheap. The *Demand Report* option shows what has been moving.

### Bronze tier — crafting materials

<table class="table" id="bkmrk-item-base-price-iron"><thead><tr><th>Item</th><th>Base price</th></tr></thead><tbody><tr><td>Iron</td><td>3 Bronze</td></tr><tr><td>Steel</td><td>5 Bronze</td></tr><tr><td>Elunium</td><td>4 Bronze</td></tr><tr><td>Oridecon</td><td>4 Bronze</td></tr><tr><td>Phracon</td><td>2 Bronze</td></tr><tr><td>Trunk</td><td>2 Bronze</td></tr><tr><td>Emveretarcon</td><td>4 Bronze</td></tr></tbody></table>

### Silver tier — consumables

<table class="table" id="bkmrk-item-base-price-whit"><thead><tr><th>Item</th><th>Base price</th></tr></thead><tbody><tr><td>White Potion</td><td>2 Silver</td></tr><tr><td>Blue Potion</td><td>3 Silver</td></tr><tr><td>Speed Potion</td><td>4 Silver</td></tr><tr><td>Box of Thunder</td><td>5 Silver</td></tr><tr><td>Anodyne</td><td>2 Silver</td></tr><tr><td>Aloebera</td><td>2 Silver</td></tr></tbody></table>

### Gold tier — upgrade materials

<table class="table" id="bkmrk-item-base-price-enri"><thead><tr><th>Item</th><th>Base price</th></tr></thead><tbody><tr><td>Enriched Oridecon</td><td>5 Gold</td></tr><tr><td>Enriched Elunium</td><td>5 Gold</td></tr><tr><td>HD Oridecon</td><td>8 Gold</td></tr><tr><td>HD Elunium</td><td>8 Gold</td></tr><tr><td>Carnium</td><td>10 Gold</td></tr><tr><td>Bradium</td><td>10 Gold</td></tr><tr><td>HD Carnium</td><td>15 Gold</td></tr><tr><td>HD Bradium</td><td>15 Gold</td></tr></tbody></table>

*Base prices are the starting point, not what you will pay. Check the live menu.*

## Exchange rates

The Market converts coins in both directions. Going up the ladder is free. Coming back down costs a 10% fee, on purpose — it stops coins being cycled for profit.

<table class="table" id="bkmrk-up-%E2%80%94-no-fee-down-%E2%80%94-1"><thead><tr><th>Up — no fee</th><th>Down — 10% fee</th></tr></thead><tbody><tr><td>50,000 Zeny → 1 Bronze Coin</td><td>1 Bronze Coin → 45,000 Zeny</td></tr><tr><td>5 Bronze → 1 Silver</td><td>1 Silver → 4 Bronze</td></tr><tr><td>5 Silver → 1 Gold</td><td>1 Gold → 4 Silver</td></tr></tbody></table>

So one Gold Coin is 25 Bronze, or 1,250,000 Zeny if you buy it outright. Earning coins is almost always cheaper than converting for them.

## Where coins come from

- **Tidemark Bounty Board** — 2 / 4 / 6 Bronze by bounty tier, plus a standing bonus.
- **Lore Story Quests** — every chapter pays Bronze; finishing all five adds a 10 Bronze bonus.
- **The Choir Roster** and **Signs on the Tide** — Bronze on completion, and the Saltwalker sells hints for a single coin.
- **Poring Haven** — Crown Couriers and Tide Couriers carry Bronze; rally milestones pay out at 50 / 150 / 400.
- **The Sundered Forge** — Bronze alongside Red Blood and Burning Hearts.

Your **Harbor Reputation** changes these payouts — Marine rank and above add Bronze to bounties, and Saltwalker discounts what the Company charges you.
