What is this and where did this coin come from exactly?

Not sure if this is the right board, but my mother recently found this coin at the bottom of a jewelry box, and I can't find any info on it, like where it came from and what this kind of coin is actually called.
Quarter for comparison.

This side of it says, from top to bottom:
Liberty
New York State American Revolution
Bicentennial
1776 ~ 1997

There's also the small symbol in the bottom right of the coin, which is of the two people holding spears and an eagle on the top of a what looks like a shield which I've seen on old version of silver quarters, just don't know the name.

Here's the other side, I think it's George Washington along with the same years of 1776 and 1997 on either side of him. I know all about American history and that's when the Bicentennial was celebrated. I'm just curious of the symbolism, face value, and origin.
