Whatever the subtype, all quarter eagles struck between 1808 and 1834 carried the same composition, which had been established under the Coinage Act of 1792. This was 91.67% gold, and 9.23% of copper and silver.
The diameter for the quarter eagle during this time period was altered on many occasions. For the 1808 Quarter Eagle, the diameter was 20 mm. After a gap in production, the denomination carried a diameter of 18.5 mm from 1821 to 1827. Finally, after the adoption of new minting technology, the diameter was adjusted to 18.2 mm from 1828 to 1834.
Regardless of diameter, all subtypes weigh 4.37 grams (67.44 grains) and have a reeded edge.
Adjustment marks are sometimes seen on the 1808 issue, but are virtually unheard of with the later dates. The quarter eagles struck between 1829 and 1834 are the most standardized, having been produced with more modern machinery.
