Liquidum : the Interstellar currency

Hi All,

Liquidum is the interstellar 'hard currency' operating in a similar fashion to the gold standard on earth between 1870 and 1914. Liquidum cannot be replicated and is rare (to be specific the location and mining of it makes it rare, relatively speaking at a universe level), sometimes found on asteroids and planetary bodies, but mostly in nebula and other super nova remains (pulsars, neutron stars) . It is as the name suggests a liquid similar to water, the only problem it is toxic and radioactive to many species, so it is encased in gold (as a radiation shield).  Almost all currencies are tied to specific amounts of this liquid although, both there are both digital (the equivalent of bank notes which must be converted in the physical stuff on demand) and actual physical currency floating around. The most common formula is the Byzantine standard of £ :

1 Libra (£) contains 1 pint of liquidum and is encased in what looks like a golden house brick (hence the knickname 'brick') .

1 Barr contains 1 Fluid ounce of liquidum and is encased in what looks like gold bars or ingots  (nickname bar without the extra b) .

1 Piastre contains 1 fluid scruple of liquidum and is encased in a gold coin. 

There are other subdivsions and coins, but these are the main ones. Thus there are 480 Piastre to a Libra. There are 20 Barrs to a Libra and 24 Piastre to a Barr.

Humans have linked their currencies to this Liquidum, but all major currencies had to undertake a significant revaluation in an attempt to match parity with the Libra. Thus in 21st century terms :

1 new USD was worth 24,000,000  old ones

1 Mark was worth 50,000,000 old Euros 

1 new Pound Stirling (which also ditched decimal) was worth £15,000,000 old ones. 

Thus the entire economy of the US was 800,000 Bricks, Europe 1,300,000 Bricks and the UK 160,000 Bricks.
