Reverse description	A large, fully spread butterfly is depicted in vivid holographic treatment occupying nearly the entire coin field, its wings displaying iridescent rainbow colors shifting from blue and violet to gold and orange depending on the viewing angle. Circular eye-spots are visible on both the upper and lower wing pairs, rendered with fine detail. The hologram technique creates a striking prismatic effect across the entire reverse surface.
