It's impossible to get any silver from buffalo nickels. They were all minted from the same metal, an alloy of 25% nickel and 75% copper.
The ONLY US nickels that ever contained silver were special "war nickels" minted from late 1942 to 1945. They were made of an alloy of 56% copper, 35% silver, and 9% manganese because nickel metal was needed for the war effort. These coins are distinguished by a large mint mark letter over the dome of Monticello on the back.

All US nickels from 1866 to date weigh 5 grams.
