For most of the early 1800s an American gold coin held more gold than its face value. Bullion dealers and exporters took the coins to Europe and melted them, so quarter eagles and half eagles hardly circulated at home. Congress fixed the problem with the Coinage Act of June 28, 1834, which took effect on August 1. The quarter eagle dropped from 67.5 grains to 64.5 grains, about 4.18 grams, and its fineness from .9167 to .8992. The old coins, now worth more than $2.50 in gold, came back to the Mint to be melted and recoined.
The Mint wanted the new coins to look different from the old. Treasury Secretary Levi Woodbury suggested inscribing the date the law took effect; Mint Director Samuel Moore objected and recommended instead that the motto E PLURIBUS UNUM be dropped from the reverse, which is what happened. Chief Engraver William Kneass also gave the obverse a new portrait. His Liberty, with loose curls held by a band reading LIBERTY, is generally seen as an adaptation of the Classic Head that John Reich had designed for the cent and half cent decades earlier. The portrait was adjusted several times before 1839, partly by Christian Gobrecht, who joined the Mint after Kneass suffered a stroke in 1835.
The lighter coins stayed in circulation, and production rose sharply. Philadelphia struck 547,986 quarter eagles in 1836 alone, and the Classic Head total from 1834 to 1839 came to 968,228. A law of January 1837 set the fineness of all gold coins at exactly .900, so the coins of 1837-1839 are very slightly finer than those of 1834-1836.
The design also carried the first branch-mint quarter eagles. Charlotte, North Carolina, and Dahlonega, Georgia, had been given mints to coin the gold of the Southern gold rush, and New Orleans a third. Charlotte struck Classic Head quarter eagles in 1838 and 1839, and Dahlonega and New Orleans in 1839. In 1840 Gobrecht's Liberty Head, already in use on the eagle and half eagle, replaced the Classic Head on the quarter eagle.
