Oh, dude, the US mint started adding copper to coins in 1793. Yeah, like way back when George Washington was probably like, "Hey, let's make our coins a little more blingy with some copper." So, yeah, 1793, when the US was just a baby country trying to figure out its fashion sense in the coin world.
Copper-nickel coins for the dime and quarter started with coins dated 1965. The half-dollar remained 40% silver from 1965-1970 when it was changed in 1971 to copper-nickel removing all the silver of it.
In 1964, the US mint was making coins primarily at two sites, Philadelphia and Denver. To distinguish the coins, the Denver coins had a D under the date. The Philadelphia coins had no mint mark.
The first coins made by the US Mint was in 1793.
Asuming no mint mark $17.00-$25.00 for circulated coins depending on the grade. Mint state coins start at $30.00+
Current retail values are $15.00-$24.00 for circulated coins. Mint state coins start at $28.00
The last copper coins minted by the Royal Mint were minted in 1860. Since then, "copper" coins have been made from bronze which, depending on the year, has a copper content of anything between 92% and 98% copper. More recently, in 1992, the Royal Mint changed from bronze 1 Penny and 2 Pence coins, to more cost effective copper plated steel coins.

2p coins were made of bronze from their introduction until 1992, when the rising price of copper forced the Royal Mint to start making the coins from steel with a thin copper plating.
To make copper harder for use in 2p coins in 1991, the Royal Mint began adding nickel to the alloy. The addition of nickel increased the coin's durability and resistance to wear, making it suitable for continued circulation.
The first coins made by the US Mint was in 1793.
The copper plating was not done by the U.S. Mint so the coin is just face value. NOTE: No U.S. Mint plates any coins with copper, gold or silver.
The Royal Mint has not produced a purely copper coin since 1860 when they changed to bronze for making "copper" coins. The bronze consisted of 97% copper, 2.5% zinc and 0.5% tin. All British "copper" coins are now made from copper plated steel. The Royal Mint does not produce any purely nickel coins either, but coins made from an alloy of 75% copper and 25% nickel. Of the two, the copper/nickel coins would last a little longer. The Royal Mint expects to get 40 to 50 years use out of its coins before they recycle them.
1947 is the first year for Mint Sets.
The United States stopped minting silver coins for circulation in 1964 due to the rising cost of silver. However, the U.S. Mint still produces commemorative silver coins and bullion coins for investors and collectors.

Yes they are, all "S" Mint 1971 & 1972 Eisenhower dollars are 40% silver, but ONLY for those two years. In 1973 the Mint added copper-nickel clad "S" Mint coins along with the 40% "S" Mint silver coins
