Facts About US Silver Coins
All of the US dimes, quarters, half-dollars and dollars that were minted for circulation in 1964 or earlier contain 90% silver by weight. Kennedy half-dollars produced from 1965-to-1970 contain 40% silver. During World War Two, Jefferson nickels were minted with a 35% silver content, and may be recognized by the large mint mark (P, S or D) above the dome of Monticello on the reverse. Additionally, some special coins minted in the 1970s and marketed to collectors had a 40% silver content, to include some S-mint bicentennial and proof sets and some S-mint Eisenhower dollars; all of these rarely entered circulation, and may be identified by their greyish edges as opposed to the copper-band edges of normal clad coins.
The silver content by weight in troy ounces for the US circulating silver coinage is as follows:
|Silver Coin Types||Silver (oz.)|
|War Nickel (1942-45)||0.0563|
|40% Silver Half-Dollar (1965-70)||0.1479|
