The Quasi Universal Intergalactic Denomination (QUID) is a proposed "space currency" created as a viral marketing campaign launched by Travelex with the London-based public relations and advertising firm, talkPR.

The end result was a series of circular clear discs with colored centers, symbolizing the eight planets of the Solar System inside, and denominations ranging from 1 to 10.

[1] Travelex stated it planned to work with the Bank of England to begin registering the QUID as possible legal currency in the future.

[1][2] The campaign was launched in the midst of intense press coverage of the Virgin Galactic news.

[6][7] Science magazines and technological blog writers weighed in on the topic, calling it "useless" and "nonsense", further spreading the story.
