Looking at the front of the coin, the mintmark is just above SBA's shoulder, on the left side.

Priceless, if it has Miss Liberty on it. But the last Liberty Head silver dollars were minted in 1935. Your coin isn't silver and it has a picture of Susan B. Anthony, not Miss Liberty. Please see the Related Question for more details.
Although older silver dollars (1794-1935) all have a symbolic bust of Miss Liberty of different types on the front of the coins, no US one dollar coin is called just a "Liberty" dollar neither are the modern dollars (1971 to date) which do not have Miss Liberty on them. By the date 1979 your coin is a Susan B. Anthony dollar and none of the SBA Dollar coins struck for general circulation (except the 1979-P Near Date) have more than face value and none of them were struck in silver. Only proof and uncirculated collectors coins sold from the Mint have premiums.
From $1 to $7,500 depending upon the mint mark, variety and the condition of the coin.
None of the coins listed in this question contain any silver or gold. All are just face value.
Other than the fact that a 1979 SBA dollar coin is about the size of a quarter, a Liberty Lobby coin is a large 1 ounce silver round with the LL logo on the reverse.
