See Resources (for Resource buildings)
There are four types of Currency in the game; Resources (Metal, He3 and Gold); Mall Points (the Premium currency); Tokens (Badges/Honor/Champion points, collected to buy special items) and Vouchers (a limited currecncy).
Like most Freemium games, the Premium currency 'Mall Points' can be used to aid you in pretty much everything from Research, ship production and speed up upgrades and so forth, there are also Vouchers which can be used to speed up Research and Building Upgrades and purchase a few (very limited) items from the Web Mall (the games shop), these are free and are given (in a small amount) as a daily collectable.
Resources[]
The 3 resources in Galaxy Online II are:
Metal - Produced by Metal Collectors, usually the smallest resource produced which is primarily used to manufacture ships, it is also required for building upgrades. (0.4 of gold production rate)
He3 - Pruduced by He3 Extractor, the second highest produced resource which is primarily used to fuel ships, it is also required for building upgrades. (0.5-0.6 gold production rate)
Gold - Produced by Residential areas, produces the most income and is used for Research, trade, and is also required for upgrading buildings. (~2x more produced than metal or he3)
All resources are stored in the Resource Warehouse, which has limited capacity requiring the player to collect from it every 12 hours or less, see also trading center for more about gold.
All 3 of these resources can also be obtained from attacks on other players.

Mall points - The game's Premium currency. Can be used to purchase a wide variety of items from both in-game shops and other players. In order to sell an item to another player for mall points, a minimum amount is required to be purchased from IGG due to the auction placement fee.
Vouchers - These are similar to mall points, but you cannot buy many mall items with them, they also cannot be donated to the corp. Vouchers are difficult to get in large quantities, but are useful in and are free.
