20 Antarctic Dollars South polar skua

The Antarctic Banknote Company is a private novelty issuer with no monetary authority, no central bank relationship, and no legal tender status in any jurisdiction. These notes circulate as collectibles and souvenirs, not currency. The South polar skua series was produced on polymer substrate — an unusual material choice for a novelty item, typically associated with circulating issues from De La Rue or Note Printing Australia, and here likely chosen to signal production quality to collectors rather than for any genuine durability requirement.

The holographic foil strip is decorative. No central bank mandated it.
