There is no predetermined limit for coins minted for general circulation. The number of coins made for the year depends on the economy.
1964 was the last year for 90% silver coins and 1970 was the last for 40% silver coins. Special Bicentennial (1776-1976) collectors coins were made in 40% silver. From 1992 to date proof collectors coins have been struck in 90% silver.
1932 was the last year gold coins were struck for circulation.
Quarters and most other silver US coins contained 10% copper; the last coins made of that alloy were dated 1964. The US has never made solid silver circulating coins. Pure silver is far too soft for use in coins, so it was always alloyed with copper for hardness.
12 Billion only if you include nickles

Dollar coins in the United States stopped being made of silver in 1935. The last silver dollar coins were the Peace dollars, which were produced until that year. After 1935, dollar coins were primarily made of a copper-nickel alloy. The move away from silver was part of a broader shift in U.S. coinage during the Great Depression.
