Not sure, but if it is a city, the street at an angle looks a lot like Broadway right at time square. No clue what coin it is though.

Great coin! And I had the wrong triangle , that looks like Canal street, pretty cool how exact the design is.
BTW - That close up is of Liberty Street and Maiden Lane, not far from Chase Manhattan Plaza, where the Federal Reserve Bank happens to be.
