2. Statue of Liberty

The Statue of Liberty is made of copper (3/32 of an inch thick, in fact) and when it arrived, it was just like the color of the penny. Reports vary as to when the Statue of Liberty started to turn green (from oxidation), but the New York Historical Society reports that the Statue of Liberty was fully green by 1920 based on vintage postcards. By 1910, it was half brown and half green.
