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.

Yes, Europe does, Its 15 or so yellow stars on a blue background. (The number has changed based on the number of members in the European Union.) This is the flag set for the European Union. Australia has a country flag which also serves as its continental flag. Antarctica has a few flags, the principle one being a sky blue flag with the white continental shape of Antarctica. Africa's flag is represented by the African Union flag, a green flag with a white stripe in the middle and a yellow image of Africa in the middle of the white stripe. South America recently adopted a white flag for Unisal, the South American Union. Only Asia and North America lack continental flags.

All research stations fly the flags of the countries that support the station. There is no sovereignty on the continent and there is no official Antarctic flag. As well, there are no Antarctic stamps, or currency. Claiming nation-states do issue commemorative stamps and include Antarctic images on their currency, as ways to maintain their territorial claims.
