The $2.5 Gold Classic Head Quarter Eagle is a U.S. coin that was minted from 1834 to 1839. It features a left-facing bust of Liberty wearing a headband inscribed with "LIBERTY," known as the "Classic Head." This design was created by Chief Engraver William Kneass or perhaps by Christian Gobrecht. Notably, the Classic Head design represented a departure from the previous "Capped Bust" imagery and the coin's composition was also changed during this era to a standard of .900 fine gold as a result of the Coinage Act of 1834, which sought to adjust the coinage in response to the increasing value of gold.
