It depends on a couple of things. No silver dollars were minted in 1979. The Susan B. Anthony dollar, which was minted from 1979 to 1981 and again in 1999. They were minted in a copper-nickel alloy. Most of them are worth only $1, but certain coins were minted in proof. The proof pieces have a small 'S' mint mark.
