Silver coins were issued from 1794 to the mid-1960s so that's an extremely broad question!
To give a general answer, most silver coins issued up till the 20th century carried a picture of Miss Liberty, although there were a couple of exceptions.
Her picture was gradually replaced on silver coins when the Presidential series started:
> Quarters - 1932 (Washington)
> Dimes - 1946 (Roosevelt)
> Halves - 1948 (Franklin [not a president], then Kennedy)
The FACE value is the same as all other US coins set by the denomination.
Simple answer: The price of silver on the international market got so high that the coins were worth more than face value.
Inflation caused the silver content of coins to be worth more than their face value so the US mint stopped making silver coins for circulation.
