Balonia was a country.
Description[]
A country which minted coin such as nickels, Balonia had long ceased being an independent nation by the early 1950's when Scrooge McDuck sought to con Donald Duck out of a payment by paying him in Balonian money, which he assumed was worthless. Instead, however, the coin's rarity meant a Balonian nickel was now worth 5 dollars.
Where Balonia used to be, and the circumstances of its loss of nation-status, are both unknown, though it is possible that it has some connection with the Duke of Baloni's family, which would place it somewhere in or around Italy.
Behind the scenes[]
Balonia was mentioned in the 1954 story Secret of Atlantis.
