If you are at that, it's worth noting that the currency tag consists of three capital ASCII letters. That would be fifteen bits, take or give. That leaves fourty-eightish bits for the number or about 10^14. THis is only half-serious, since there are other problems with currencies (their value is dependent on time, all that Pandora's box).
