Gilla

Gilla is the standard currency used by Earth an the colonies in the Universal Century. It is not known what the exchange rates for gilla to conventional currencies are, nor is it revealed if gilla has a physical form or if that is in bill or coin.

The term "gilla" first appeared in Gundam ZZ and was the first refernce to a specific currency rather than just a vague term such as "money". It is brought up by Judau's companions. It was brought up again when Taman and his fisherman companions charged the Argama 2,000 gilla in order to lead them to a safe harbor.
