A system and method for non-deterministically providing denominated virtual currency in a virtual space are disclosed. The units of virtual currencies may be classified by different denominations and levels. Non-purchasing utilities may be obtained for the denomination and level of the virtual currencies and provided to users in the virtual space. In one example, the denomination and level of the virtual currencies may be used as socketing elements to provide boosts to base attributes to virtual items. In some implementations, an amount of boost provided by a denomination and level of virtual currency when socketed to a virtual item may be determined based on numerical relationships among the denomination and level of the virtual currencies. The denomination and level of virtual currencies may be harvested non-deterministically by users based on probabilities determined for the users.
