May be a sign of the times, but people are bidding on ebay for fake currency used as props on the SciFi Channel show Battlestar Gallactica:
A 100 Cubit Note is going for $132.50 (current bid), so that means a *fictional* 1 Cubit is worth $1.32 US currency.
Euro = $1.25
British Pound = $1.41
So ... The economic worth of a fictional currency (of a society decimated by Cylons no less with only 47,000 survivors) is worth somewhere between the Euro and the British Pound. I think it's mainly because the Cylons look like this now.
