The Grant Memorial coinage are a gold dollar and silver half dollar struck by the United States Bureau of the Mint in 1922 in honor of the 100th anniversary of the birth of Ulysses S. Grant, a leading Union general during the American Civil War and later the 18th president of the United States. The two coins, identical in design and sculpted by Laura Gardin Fraser, portrayed Grant on the obverse and his birthplace in Ohio on the reverse.
The Ulysses S. Grant Centenary Memorial Association, also called the Grant Commission, wanted to sell 200,000 gold dollars to be able to finance multiple projects in the areas of Grant's birthplace and boyhood home. Congress authorized only 10,000 gold coins, but also authorized 250,000 half dollars. Hoping to boost sales, the Grant Commission asked for 5,000 of the gold dollars to bear a special mark, an incuse star; the Mint did the same for the half dollars as well, unasked for.
All the gold dollars and most of the half dollars were sold, although some half dollars were returned to the Mint for melting. The half dollar with star has long been priced higher than most commemoratives; its rarity has also caused it to be counterfeited. Money from the coins was used to help preserve Grant's birthplace, but other planned projects were not completed.
