http://wiki.answers.com/How_can_you_tell_a_coin_is_not_pure_silverCirculationUS Coins were never made of pure silver. Up through 1964, dimes, quarters, and halves were made of 90% silver with 10% copper added for hardness.
In any case it's essentially impossible to refine silver to 100% purity. Even ultra-pure silver bullion "coins" have traces of other metals in them.
