Designed by Adolph A. Weinman, the Walking Liberty Half Dollar was minted from 1916-1947. The mintmark appears on the obverse under the motto, “In God We Trust”, on the 1916 and some 1917 issues. The mint mark was then moved to the reverse near the rim at the 7 o’clock position. 1917 issues have either obverse or reverse mint marks. The Walking Liberty Half Dollar is widely considered to be one of the most beautiful United States coins.
