Seated Liberty Dollars
The specifications for the Seated Liberty Dollar remained constant for the duration of the series from 1840 to 1873. Interestingly, there were some periods of the series when the melt value of the coins exceeded the face value, which had an impact on production and circulation, and in some cases led to melting.
Designed by Christian Gobrecht, the obverse of the coin features an image of Liberty seated on a rock. She holds a pole with a cap in one hand and a shield with the word “Liberty” in the other. There are thirteen stars surrounding and the date below. The style and pose of Liberty is said to be reminiscent of Britannia from British coinage. On the reverse is a bald eagle with a shield at the chest, and with arrows and talons grasped in its claws. The inscriptions are “United States of America” and “One Dol.” In 1866, the motto “In God We Trust” was added on a scroll above the eagle.
Each Seated Liberty Dollar is struck in 90% silver and 10% copper, yielding a net weight of 0.77344 troy ounces of silver. The coins have a diameter of 38.1 mm and gross weight of 26.73 grams. The coins have a reeded edge and were struck at Philadelphia, New Orleans, San Francisco, and Carson City.
Production of the coins was officially halted following the Coinage Act of 1873.
