Currency in Runes of Magic is mainly made of these basic items: 
Gold, 
Phirius Token Coins (a.k.a. Tokens), 
Diamonds and 
Rubies.
Money[ | ]
Gold coins are the most common. They are gained in game, spent in game, used for most trade between players and the game, and players between themselves. Gold Coins are owned by a character.
Diamonds are a special currency. They are bought outside of the game, with real money. They allow you to buy some very useful or exotic items that can only be bought with Diamonds, in the Item Shop. They are occasionally sold and bought in game, from one player to another, but are particularly expensive. Diamonds are owned by a player account on a server. They are shared between all the characters of the server.
Rubies are similar to diamonds except they cannot be bought. They are used to buy items from the Ruby Shop section of the Item Shop. Rubies are shared between all characters of a server. You get rubies by buying items from the Item Shop. They can be thought of as fidelity coupons. Rubies are no longer available but those owned by players may still be spent.
You get 
Phirius Token Coins from doing Daily Quests. Tokens can be used to buy items from certain NPC's in game or from the Phirius Token Shop section of the Item Shop. Tokens can also be used to enter Malatina's Survival Game or Malatina's Course of Terror.

Currency Wallet[ | ]
A special tab under your (C)haracter Sheet that displays all non-Money currency you have. Most of the time earned currency will go directly to your wallet but sometimes you will see some actual coins in your inventory. Simply "use" them to move them to your wallet.
