1921 Missouri Centennial. Plain. MS-66 (PCGS). CAC.A wonderfully original example with blushes of russet and pale rose to a base of antique silver patina. Boldly struck with a smooth, frosty texture. This commemorative half dollar was issued to mark the 100th anniversary of the admission of Missouri into the Union. The authorizing Act of March 4, 1921 allowed for a maximum mintage of 250,000 coins, but in the end only 50,000 pieces were struck, 5,000 with 2x4 in the left obverse field signifying Missouris status as the 24th state and 45,000 without this added feature. Lagging sales resulted in 29,600 examples of the plain variant being returned to the Mint for remelting, leaving a net mintage of 15,400 pieces. With most survivors grading no finer than MS-64, this premium quality Gem is sure to catch the eye of advanced commemorative enthusiasts.
