Depending on what country issued the coins, you have to know its denomination and date. There are reference books (e.g. the Red Book for US Coins, the Krause guide for world coins) that tell you which dates and denominations to look for.
The rules for US coins are fairly straightforward:
> Dimes, quarters, and halves dated 1964 or earlier are 90% silver, 10% copper.
> Dollars dated 1935 and earlier are 90% silver.
> Half dollars dated 1965-70 are 40% silver
> Nickels dated 1942-1945 AND with a large mint mark over the dome are 35% silver.
> Half dimes and some 3 cent pieces (both obsolete denominations) are silver.
If you have anything else among modern coins, it does notcontain silver regardless of rumors or urban legends to the contrary. For example, there has never been a silver US penny, only steel, and all other nickels except those listed are made of copper-nickel, even the ones dated before 1965.
