| 裏面の説明 | Colorized depiction of the Shinkansen E5 Series Hayabusa high-speed bullet train rendered in its characteristic teal-green livery with a pink accent stripe, advancing dynamically from right to left across the field with motion-blur effects suggesting high speed. Above, a peregrine falcon (hayabusa in Japanese) soars in flight amid green foliage and golden falling leaves against a warm yellow background. The curved legend 10th Anniversary of Series E5 HAYABUSA arcs along the upper periphery, while a gold cartouche at the bottom center bears the denomination $50, and the fineness .9999 appears to the lower right. |

The Hayabusa2 mission, operated by JAXA, successfully retrieved samples from the asteroid Ryugu in December 2020 after a six-year round trip covering roughly 5.2 billion kilometers — the first mission to deliberately blast a crater into an asteroid's surface to collect subsurface material. Cook Islands has no connection to the mission whatsoever; the issuing authority here is purely nominal, as the territory's numismatic program is administered through commercial licensing arrangements that place its name on bullion and commemorative issues globally.
The .9999 fineness corresponds to a precise troy half-ounce — 7.78 g being a standard fractional bullion increment rather than a figure tied to the subject matter.
