Current materials: Cent - 97.5% zinc plated with a thin layer of copper Nickel - A solid alloy of 75% copper and 25% nickel Dimes, quarters, halves - 2 outer layers of 75% copper and 25% nickel bonded to a core of solid copper, for an overall content of about 92% copper. Dollars - Manganese brass bonded to a copper core; overall content 88.5% copper, 6% zinc, 3.5% Manganese, 2% nickel
Currently US cents re made from zinc and copper.
Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
All modern coins in circulation are made of metal.
Up until recently, copper coins contained very small quantities of tin, zinc or even aluminium, and were perhaps more accurately referred to as bronze coins. Currently, due to the increasing cost of copper, there is a trend away from minting copper coins, and many, what were previously copper coins, are now being made from copper plated steel.
No. The US Mint uses a variety of metals in the minting of coins but lead is not one of them.
The first coins made by the US Mint was in 1793.
No U.S. coins were ever made from lead.
The only U.S. coins currently made that are silver are American Silver Eagles and other special collectors coins sold by the U.S. Mint. These coins are NOT released for circulation.
Currently just the Denver and Philadelphia Mints make coins for general circulation.

Currently US coins are made at four mints. The Philadelphia and Denver mints make coins for circulation. The San Francisco makes proof coins sold to collectors and investors. The West Point mint makes special coins that are not put in circulation and are sold to the general public.
US coins were first struck by the US mint located at Philadelphia, Pennsylvania in 1793.
Coins are produced by the US Mint which is part of the Treasury Department. The Mint currently strikes coins in 4 facilities: Philadelphia, "P" mint mark since 1979/80 on all coins made there except cents Denver, "D" mint mark on all coins made there San Francisco, "S" West Point, "W" Since the 1970s only Denver and Philadelphia have produced coins for circulation, while proof coins are made in San Francisco and special collectors' coins, bullion coins, and commemoratives are made at West Point.
After coins are made they are bagged and distributed to banks in the US through the Federal reserve system.
Your question needs to be rephrased. "Denver coins" are simply ordinary US coins (cents, nickels, dollars, etc.) that were struck at the US Mint facility in Denver.
The US has four mints that make coins. The US mints make coins in the denominations of 1 cent, 5 cents, 10 cents, 25 cents, 50 cents, and 1 dollar for general US circulation. Half dollars and dollar coins are not often used but they are legal tender and can be used in circulation. The US mint also makes bullion coins made of silver and gold. On top of that they make special coins that commemorate anniversaries of special events. These are just some of the coins that the US mints make.
