1947 is the first year for Mint Sets.
The Mint produces a full range of coins almost every year to keep a sufficient amount of coins in circulation.
If you mean U.S. coins? The Philadelphia Mint started making coins in 1793, they were cents and half-cents. The first One Dollar coin was made in 1794.

The U.S. Mint does the actual making of the coins.
Coins are manufactured at a "Mint" which is usually under the control of the government.
The first coins made by the US Mint was in 1793.
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.
There is no company that mints Canadian coins. The coins are minted by the Canadian government, not a company. The government entity in charge of minting Canadian coins is the Canadian Mint.
The US Mint, which is part of the Department of the Treasury, produces US coins.
Perhaps by a private mint but not by a government mint.
