Latinum

Latinum is a silver liquid that due to its scarcity and the fact it cannot be replicated is used as a form of currency in the Alpha and Beta Quadrants. For ease of transactions latinum is encased within gold.

The lowest common denomination of latinum used is a slip of latinum. The next highest is a strip of latinum, which is equivilant to a hundread slips. This is followed by a bar, which is equal to twenty strips or two thousand slips. The largest known denomination is a brick. 

Terri Renu managed to raise just over two bars of latinum over a two - three year period. With this she was able to hire a person to retrieve information about her Bajoran heritage.
