Emily Bucks are a form of currency that is nearly worthless due to mass inflation and being extremely volatile. Emily bucks can be used to purchase dark nuts, light nuts, deku nuts and are often counted in base-2. At the current time, it costs E$80,000 for a high-five from Emily Axford and E$100,000 to receive a dark nut (whatever that means). Although being nearly worthless at the current time, market analysers believe emily bucks could see a recovery in the near future and are investing large amounts in hopes to make a profit.
Emily bucks were first mentioned in Episode 22 - Legend of Zelda Adventure Book: The Shadow Prince where the gang managed to collect 79,818 Emily Bucks for their successes.
