This is a One Pound Note (£1), a variation of the Great British Pound printed by the idiosyncratic government of the equally idiosyncratic tiny island that i live on. The Bailwick of Jersey basically has their own printing department where they print their own paper notes, as well as coins. They literally print their own money so to speak.
Ironically, if you were to take examples of this currency to Great Britain and try and use the money anywhere in Great Britain, although being completely legal tender, your money will be rejected. I remember being a uni in Liverpool,
and trying to give bus drivers £1 notes or 10 p coins, and being told off.
The money can be changed in most banks though.
Also can be used when playing Monopoly. A game that some of the wealthier wealth supremacists in the island play in real life. but instead of just a fun game where no one gets hurt, people die on this "perfect" paradise island.
Perfect, for some, not necessarily for the local inhabitants. ...
