Found One!

The DC quarter was released in January. (I was very excited, even with the modified design change.) Which means in January I started bugging cashiers. Using bills to get as much change as possible. (I am also making the Coinstar people happy). By summer I was ready to spout conspiracy theories, but then someone got one, so I knew they did exist, I just had to acquire one. I actually got a Puerto Rico one first.
But now, finally, cashiers in the area can relax.
