Here is a design of new currency i came up with.
Ohh, a promissory note. Now what can it be exchanged for…? Nothing so mundane as gold i suppose?
What would the Bank of Hell own that would back up the worth of that note?
Human skulls of course, they are limited so they can’t be reproduced aimlessly and while technically common, is very rare.
They are not actually that rare. Problem is most of them are wrapped up in this annoying bloody thing called flesh and are in use.
Maybe the dead shall know of that size currency.
Maybe the human skulls maybe made of a rare form of iridium.
