If I'm correct, that's a beautiful 1792 Eagle, anon. The Coinage Act of 1792 exercised Congress's power to Fix[] the standard of weight[] and measure[] of the U.S. Dollar as being "of the value of" 371 and 4/16 grains of fine silver as in the Spanish Milled Dollars now current. It also fixed the weight of the "Eagle" as 247 and 4/8 grains of fine gold. According to the relative value of gold and silver at the time of the 1792 Act, the value of the "Eagle" was Ten "Dollars" – the "Dollar" being a value denominated in Silver.
NOTABLY, however, the Eagle DOES NOT have a face value denominated in "Dollars". This is because "Dollars" ARE NOT GOLD. "Dollars" are "Coins" containing 371.25 grains of silver.
