Composition and Specifications


Under the Coinage Act of 1792, the eagle was established as the largest gold denomination with a value of ten dollars. The composition was specified as 91.67% gold and 8.33% silver and copper. The coins have a standard diameter of 33 mm and weight of 17.50 grams, although some variation is possible. All coins have a reeded edge.

As with other early gold and silver coins, adjustment marks are often encountered. These were made by the mint to adjust the weight of planchets closer to the standard. While these marks typically do not have an impact on value, early eagles without adjustment marks or barely noticeable marks are typically preferred by specialists. Most pieces are well struck, although some weakness is usually noted at the centers.
