Looney

A looney was a type of coin, equal to one dollar, that was used in Canada during the 20th century through the 22nd century. It features the image of a loon on one side, and the head of the current monarch of Canada on the reverse.

Michael Eddington kept what he referred to as a "lucky looney." It had been a family heirloom for over two hundred years. He left the looney, 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.
