1921 Standing Liberty Quarter. MS-66 FH (NGC). Exceptional premium Gem Mint State surfaces display razor sharp to full striking detail throughout the design. Brilliant with a delightful silver-white appearance. With a mintage of 1,916,000 pieces, the 1921 has long been regarded as a key date issue in this series. Attractive Mint State survivors in any grade are challenging to acquire. Only 5% of the mintage has Full Head definition (per J.H. Cline, 2007), and the opportunity to acquire a sharply struck Gem usually comes along only once in a very long while. The present coin represents an important opportunity for Standing Liberty quarter collectors. From the Larry H. Miller Collection. From the Larry H. Miller Collection.
