Geiconian Currency

Geiconian currency (unofficial name) is a system many games use for their in-game currency in which a "base" currency can be bought with another more valuable currency. This more valuable currency can be bought with money. The base currency is called the Tier I currency, and the more valuable currency is called the Tier II currency. Tier I currency may be bought with money too.

Coins and gold are common names for Tier I currency. Gems and diamonds are common names for Tier II currency. In Cookie Clickers 2, Cookies are the Tier I currency, and Golden Cookies are the Tier II currency. Golden Cookies can be bought with money in the Bank. Cookies can be bought with Golden Cookies in the Time Machine.

The term 'Geiconian currency' is a coined term. We all see Geiconian currency in many games, but it has never been named, so I decided to coin the term "Geiconian currency".
