Acceleration from gravity is 9.8 m/s2 or 32.2 ft/s2.
The Empire State Building is 381 meters/1,250 feet tall. So if we throw a penny off the Empire State Building, its speed would increase by 9.8m/32.2ft every second.
We will count every second's increasing speed.
9.8m for the first second.
32.2ft for the first second.
We keep adding 9.8m to the speed for every second that passes.
We keep adding 32.2ft to the speed for every second that passes.
On the eighth second, the penny will have passed 352.8m or 1157.5ft. The current speed for the ball is 78.4 m/s or 257.2 ft/s. We increase that by half of 9.8 m/s or half of 32.2 ft/s (4.9 m/s and 16.1 ft/s). The speed of the penny will now be 83.3 m/s or 273.3 ft/s. There is 28.2m or 92.5ft. This value divided by the current speed is 0.34. This will be the seconds left before impact on the ground.
8 + 0.34 = 8.34
It will take a penny 8.34 seconds to hit the ground when dropped from the Empire State Building. Terminal Velocity would slow it down much before it reached that point.

What would happen if you dropped a penny off the Empire State Building and it made it to the ground?
If you drop a penny off the Empire State Building, it falls at its own terminal velocity after falling about 200+ metres (that's a guess but it's around 200). A penny's terminal velocity is roughly half of a falling person's terminal velocity. A falling skydiver will reach a maximum of around 130mph, so a penny will fall at approximately 65mph.
