1/2 Dollar - Elizabeth II 100th Anniversary of the Walking Liberty Half Dollar

The Walking Liberty design originated with Adolph Weinman in 1916, the same year the U.S. Mint overhauled nearly its entire circulating coinage. Weinman won the half dollar commission in competition with Hermon MacNeil and Albin Polasek, and his design went on to circulate for over three decades before being retired in 1947. Cook Islands has no organic connection to that history — this is a bullion-adjacent commemorative riding the centennial anniversary, issued under the broad licensing arrangements that have made the Cook Islands one of the most prolific third-party commemorative issuers of the modern era.

The .9999 fineness is finer than the original 90% silver planchets Weinman's design ever struck on.
