bullseye, its a mainly copper coin plated with nickel (2%) manganese (3.5%) copper (88.5%) and Zinc (6%) to give it that golden color. Its not a collectors coin, technically speaking its a circulation coin that no one bothers to circulate (similar to the US half dollar). Some collectors still add them to thier collection.
I should add, this coin is known as the presidential series. It stated in 2007 with George Washington. This coin commemorates the 9th president William Henry Harrison.This specific coin was released in early 2009.
