To ensure the quality of each 2015-W American Liberty, High Relief $100 gold coin struck at the West Point Mint, each planchet will be hand-fed and manually retrieved one at a time from the coinage press.
The American Liberty coin is the first U.S. gold coin to bear a face value of $100.
According to U.S. Mint officials, each coin is to be struck three times on a Gräbener GMP360 coinage press with the dies striking vertically. Each strike is scheduled to exert approximately 100 metric tons to bring up the desired relief.
The dies will be oriented with the obverse, depicting Liberty in a flowing gown, as the upper or hammer die, and the eagle embellished reverse as the lower or anvil die.
The coin is being struck with a reeded edge.
The coin is to exhibit a “business strike” finish similar to that executed for the 2009-W Saint-Gaudens, Ultra High Relief gold $20 coins, a finish traditionally referred to as Uncirculated.
The U.S. Mint provided Coin World with detailed production specifics for the 2015-W American Liberty, High Relief 1-ounce .9999 fine gold coin after submission of multiple questions.
The American Liberty, High Relief gold $100 coin goes on sale at noon Eastern Daylight Time July 30. The maximum issue is limited to 50,000 coins.
The initial pricing for the coin is to be announced during the week beginning July 13, according to Mint officials.
A companion High Relief 1-ounce .999 fine silver medal bearing the same designs but without coin inscriptions is to be offered at a later date.
