Looney
A looney, or loonie, was a type of coin, equal to one dollar, that was used in Canada during the 20th century through the 22nd century. First issued in 1987, it featured the image of a loon on one side, and the head of the then-current monarch of Canada on the reverse.

Michael Eddington kept what he referred to as a "lucky loonie." It had been a family heirloom for over two hundred years, as of 2373. He left the loonie, along with other personal items, on Deep Space 9 when he joined the Maquis. Benjamin Sisko believed it might have been placed in an assay office locker after his defection. ()
