so, will a penny dropped from an aircraft fall faster than a baseball?

Terminal velocity is dependent on the cross section of the object and its mass.
Assuming a coin has a crossection of 2cms, thats 0.0004m^2 and a weight of 0.009kgs, the baseball 0.14Kgs and 0.05m^2.
Assuming a drag of 1 and an atmospheric density of 1
v of coin = 21
v of baseball = 7.5
so the coin is moving at around 3 times that of the baseball at terminal velocity.

I think thousand's got it closer - a penny would probably approach terminal velocity faster at first due to it's lower drag characteristic, but turbulence would end end up kicking it about all over the place, and the baseball would over take due to it's more aerodynamic shape...
