The Vantrapolian Knuk (δ) is the main currency in Vantrapolis.
The Paper money comes in denominations of 1, 5, 10, 20 and 50. The Coin or Vash comes in 1, 5 and 10. One USD is worth 22.5 in Knuks, and the Vash is worth one-fifth of a Knuk.
The Skyvamp Dollar was used until 1930, where a new currency was formed. It was called the Canuc. The Canuc eventually became the Knuk on November 3rd 1954. During the 1960's and 70's, it went through many design changes.
It now has a portrait of the current monarch on the front and a picture of an elm tree on the back.
