Antarctic $$$
I had NO idea that Antarctica has its own currency. Actually, it doesn’t. We all know it’s a continent, not a country (right?), so doesn’t have its own legal tender. Antarctica is divided into territories, so in some parts the British Pound will buy you milk, and in others the US Dollar will pay your way. These bills are produced by the Antarctica Overseas Exchange Office, and while they may not get you far, they do fund valuable programs in that far flung place.
