Banana Republic $20 bill discovered by college student

Recently in the news is a rare U.S. $20 bill, clearly imprinted with the label off of a banana peel. In fact, it says "Ecudor" right on it. As the story goes, a college student got it out of an ATM machine. I don't know that Ecudor particularly is a "Banana Republic" (in the figurative sense), but what about the country that issued this bill, albeit mistakenly?
