Were any silver nickels made in 1959?

No. Except for special "war nickels" minted from late 1942 to 1945, all US nickels are made of the same alloy of 25% nickel and 75% copper.

War nickels 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.
