Coins

Coins is the general currency on RuneMud and has many some purposes such as shops and npc services. Most ingame items are worth so many coins and that's the basic mesuring system. Ex: Zamorak kiteshield is worth 2,000,000 coins compared to the Zamorak Platebody which is worth 3,000,000 coins. This can be used to say that 3 Zamorak Kiteshields can buy 2 Zamorak Platebodies.

Coins are used widely ingame and on the forums marketplace. In general, coins control the economy and are probably the most useful item.
