Because the US has always had a very active Mint system there's never been a need to contract with foreign mints to produce US coins.
The opposite, however, isn't the case: the US has struck coins for a number of other countries that were too small to operate their own mints, or to help during periods of high demand. For example, the Philadelphia Mint struck some 1968 dimes for Canada when that country was converting from silver to nickel coinage and didn't have enough capacity to produce all of the coins needed for the changeover.
Cent, nickel, dime, quarter, half-dollar, dollar.
Many U.S. coins have eagles. Dates and denominations are needed. Post new question.
The mint is the place where the coin was made. In the US there are several. If the coin has a D next to the date, it was minted in Denver. S is for San Francisco.
You need to provide a lot more details. The U.S. minted about a dozen different denominations in 1886 and at about a half dozen mints. Please post a new question with the coin's denomination and, if you can locate it, the mint mark.
The first US Dollar coin was minted in 1794.
The first US quarter was minted in 1796. It had a portrait of Miss Liberty on the coin.
Yes, but they were only minted in San Francisco. It was one of the few denominations minted that year. Coin production was very spotty due to low demand during the Great Depression. There's more information at the Related Question.
Please post a new question with more information. In 1891 there were 4 denominations of silver coins - dimes through dollars - minted at 4 different mints.
No such coin was minted by the US mint.
There were no US coins minted in 1776.
On the "heads" side of US coinage there is a date, that tells you when the coin was made.
If you mean the coin with the lowest denomination, since 1857 it's been the 1¢ coin, commonly called a penny.Prior to that year the US also made half-cents which are the lowest-value common circulation coin ever minted in the US.
