Navy HSM-46 HSM-79 Helicopter Strike Group Spinner Challenge Coin. Navy unit-affiliated challenge coin featuring HSM-46 “Grandmasters” and HSM-79 “Griffins” – not a reproduction or retail novelty. Functional spinner helicopter rotor, adding dynamic display appeal. Multi-unit Carrier Strike Group design including CVN-72 and escort elements. Strong collector interest for Naval Aviation, MH-60R, and Strike Group themes. This is an authentic U. Navy challenge coin representing Helicopter Maritime Strike Squadrons HSM-46 (Grandmasters) and HSM-79 (Griffins) within a Carrier Strike Group framework. The design prominently incorporates MH-60R Seahawk helicopter elements, squadron insignia, and supporting surface combatant crests, reflecting the integrated nature of modern naval strike operations. The reverse highlights the broader strike group identity with mottos “Set the Standard” and “Guardians of the Fleet, ” along with Carrier Strike Group iconography associated with USS Abraham Lincoln (CVN-72) and accompanying units. A standout feature is the fully functional spinning main rotor, making this coin particularly eye-catching for display. ? Visit My Store – Tier One Coins & Collectibles.
