Gold Coins by year from 1840 to 1810 1850
The Coinage Act of 1792 was the first law to authorize the production of gold coins in the United States of America. Specifically, it mandated the weight and purity of three new coins and denominations: the eagle ($10), the half eagle ($5), and the quarter eagle ($2.50). The half-eagle was first off the line in 1795, and the eagle followed later that year. Quarter eagles were first issued in 1796.
These denominations were still being issued as late as 1933 (more on that in a few). Each one went through a series of design changes until they settled on the Liberty Head varieties of the Victorian era. These types are increasingly popular with collectors today.
