Designed by Hermon A. MacNell, the first year (1916) of production of the Standing Liberty Quarter showed Miss Liberty with a bare breast which was covered with chain mail due to public protests part way through the second year of production. This gives us two types for the Standing Liberty Quarter in the second year (1917) of production: bare breast and covered breast. MacNell’s initial “M” can be found on the obverse to the right of the date. In 1917 the Reverse of the Standing Liberty Quarter was also changed: three of the stars on the reverse were placed under the majestic eagle and the eagle was moved for better centering. In 1925 the pedestal that Liberty is standing on was recessed in order to help protect the date. Prior to 1925 the higher dates wore of rather quickly, leaving us with Standing Liberty Quarters that will grade VG and F but without a readable date. Examples of Standing Liberty Quarters with a fully struck head are often worth a considerable premium. Examples with Full Head and well struck rivets on the shield are also very desirable. So far there is not grading terminology for “Full Shield”.
