57.How much is an eagle worth?
The Act that created the Mint called for an "eagle" in gold, worth $10. The coin showed an eagle, of course, on the back. The Act also called for a half eagle worth $5 and even a quarter eagle worth $2.50...but the whole bird still appeared on the coins. With 1849's gold rush in California came a $20 gold coin, which quickly became known as a double eagle...with one bird on it. (The United States Mint still makes gold coins, but people usually buy them as an investment rather than for spending.)
