When was the first US nickel made?
The first true US 5 cent nickel containing 75% copper and 25% nickel was minted in 1866 and was called the "Shield" nickel.Before that, the US minted tiny, 90%-silver "half dimes" to handle the 5 cent denomination. Half dimes continued to be minted until 1873, by which time there were enough nickels in circulation.Regardless of popular myths and rumors, half-dimes were the ONLY 5-cent coins to be made of 90% silver. All modern nickels except the famous "war nickels" from WWII are made of the copper-nickel alloy noted above. War nickels were minted from mid-1942 to 1945; they were made of 35% silver, 56% copper, and 9% manganese because nickel metal was needed for the war effort.

What was the last year for a solid silver nickel?
That's NICKEL, not "nickle" The U.S. only struck nickels containing silver from mid-1942 to the end of 1945. Nickel was needed for the war effort, so the coins were made from a small amount of silver mixed with copper and manganese. All other nickels from the start (1866) to today are made of an alloy of 75% copper and 25% nickel.
