If I drop a penny off the top of the Empire State building, what will happen to the penny once it hits the ground?

The terminal velocity of a penny is about 40-50 mph. 

Take a penny and throw it at the ground as hard as you can. That is about what would happen. It would hurt to get hit by one, but it would hardly cleave your skull, or the sidewalk, in twain.
