A frequent topic of speculation among McDuck fans regards the dimensions of the Money Bin. Barks defined the volume of money contained inside as “three cubic acres,” but the exact meaning, and therefore the volume, of a “cubic acre” is subject to interpretation by the reader, since an acre is a measure of area, not length. A series of blueprints created for a Scrooge McDuck story by Don Rosa state that the Money Bin is approximately 127 feet tall, and 120 feet wide. In the story, said blueprints are accredited to an architect named Keno D. Rosa, which is Don Rosa’s actual name.
