In 1917 the mintmarks on half dollars were found on both the obverse and the reverse, though beginning in 1918 they were placed on the reverse only, remaining there through the Franklin half dollar series. Though the 1917-D Reverse Mintmark Walking Liberty Half Dollar with reverse mintmark is somewhat more available in circulated grades than its obverse mintmark counterpart, in Mint State grades the reverse mintmark style is considerably scarcer and more desirable, especially in MS-65 and finer.
