OK, I missed your post #77. Except for air resistance (which is very minor) they both fall at the same rate. (Grade school physics experiment. Drop a penny and a ball from the roof of the school.)
Air resistance is not always very minor! Drop a sheet of paper flat and the same paper balled up. The ball will kill the paper. Different weight objects only reliably fall with the same acceleration in a vacuum. There are countless examples of heavier and lighter objects falling faster or slower.
As far as the penny goes, a steel ball will beat the penny. The penny will usually tumble and reach a lower terminal velocity than the ball. Drop it from a skyscraper and see what happens.
