Arkansas Commemorative Half Dollar. This 1937-S Arkansas Centennial Half Dollar is a beautiful example of early American commemorative silver, issued to honor the 100th anniversary of Arkansas’s admission to the Union. Certified as MS 64 by PCGS, this specimen exhibits the strong luster and crisp design details expected of a high-tier Mint State coin. The obverse features the striking conjoined portraits of a Quapaw Indian Chief and Liberty, while the reverse showcases an eagle perched before a rising sun and the Arkansas state flag. With a remarkably low mintage of only 5,506 pieces, this San Francisco Mint issue is a prized addition for collectors focusing on the classic commemorative series.
