Obverse, "U" in QUARTER to bottom of bust. I think this one in sort of cool, since you can easily miss it on first glance, but once you see it, hard to unsee it.
Reverse, "50 CENTS" through far left olive leaves, tip of left wing through most of "UNITE", and then again through some letters of "STATES OF AMERICA". Not the easiest coin to see a crack on, sort of blends in.
