So close, South Dakota. You almost got a "Better" rating. I like the idea of using Mount Rushmore on the quarter design because the monument is very patriotic, and it is easily recognizable the world over. It's a natural, and I think it works even on a coin-sized canvas.
But, then there's the bird, which kept this design from getting a higher rating. Again, unless your state's official bird is an eagle, a hawk, or a falcon, it has no business trying to look cool on a quarter. Or anywhere else.
