The final design of currency bills is for GEC to approve.
Earthling currency would come in following currency bills.
Billion, Half Billion, Million, Half Million, 10000, 5000, 1000, 500, and 100 Earthlings. Earthlings will generally be transacted in non-fractional numbers.
I shall provide my design drafts for Earthling currency bills directly to the GEC bills design team, once it is formed.
