Since Antarctica is governed by the Antarctic Treaty, there is no sovereignty there, no country, no state or provence, no flag, no stamps and no currency.
Coincidentally, there are no commercial ventures on the continent, meaning there's no where there to spend currency.
However, a few research stations sell notions using the currency of the country that supports the station. Their customers are all temporary workers.
Also, few stations are open to tour-boat centric tourists, and the currency these stations use reflect the government that supports the station and the currency most commonly carried by their visitors. These are different currencies: there is no standard for the continent.
Antarctica has no national currency, while the US currency is broadly recognized as a currency benchmark for work economics.
Antarctica is not a country, so does not have a 'national' animal, currency, a flag, stamps and so forth.
Antarctica doesn't have an official currency. There is no nation state to establish currency, postage stamps, flags or other items showing national ownership. Any currency, stamps, flags or so forth that purport to be 'official' anything from Antarctica are souvenirs crafted by clever entrepreneurs.
There are no countries on Antarctica, no permanent population and no currency.
There is no commerce in Antarctica, so the use of currency is minimal. When currency is used in research stations, it is the currency of the station that must be used. There is no standard currency on Antarctica.
There are no countries in Antarctica, no capitals nor any currency.
Since there is no commerce on Antarctica, there is no need for currency. As well, since Antarctica is not sovereign, there is no Antarctic currency. Any cash transactions usually occur in the currency of the research station where the transaction takes place.
Because there is no sovereignty on Antarctica, there is no national currency, stamps, flags or other icons of nationality. There are profiteers who will sell you what they call 'Antarctic currency', and these papers are souvenirs only, being useless as currency. On research stations, cash transactions are conducted in the currency of the station.
Because there's essentially no place to use currency on the continent -- no commercial enterprises, and because there is no sovereignty on the continent, there is no 'Antarctic currency'. People may purchase items, however, that are for sale and the currency used is the currency of the transaction.
There are no nations in Antarctica, meaning that there is no 'national holiday'.
