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 (the same as the monarch of the UK) on the reverse. The "loonie" (note the spelling) is a current term for the Canadian dollar coin. This was likely what the script referred to, and it was simply misspelled. Of course, the spelling convention could have changed over the course of three hundred years.
