The US didn't make any silver coins in 1979. The last circulating silver dimes and quarters were dated 1964, and the last silver halves made for circulation were dated 1969.
Despite the condition, dimes dated 1964 are so common that there's generally little to no collector value. Being that '64 was the last year for silver dimes, most were hoarded, resulting in a surplus of uncirculated specimens. Based on silver prices as of 23 May 2016, one roll of silver dimes has a melt value of $59.39.
