This coin isn't showing up on our website, and I don't know where to look for it.
However it's in worn condition so would be valued at the lower end of the scale. Some coins are still worth alot of money in worn condition.
It is from the Philippines. It is very worn. Value is $1 US dollar or so. See this page for pictures and values:
Ah! The United States bit threw me off completely! Didn't know the Philippines had coins that said that on.
