how much silver is in a 1943 nickel

[LaAdeline]

Based on established numismatic information, as the provided search context was insufficient, a 1943 Jefferson nickel contains a specific amount of silver due to its unique wartime composition. The United States altered the coin's alloy to conserve nickel, a strategic metal essential for the war effort during World War II.

A standard Jefferson nickel weighs 5.0 grams. The special wartime alloy, used from mid-1942 through 1945, consists of 56% copper, 35% silver, and 9% manganese. Therefore, a 1943 nickel contains 35% silver by weight. Calculating this amount reveals that each coin contains precisely 1.75 grams of pure silver.

These silver-alloy nickels, often referred to as "war nickels," are easily identifiable by the prominent mint mark (P, D, or S) located on the reverse side, directly above the dome of Monticello. This was the first time the "P" mint mark, for the Philadelphia Mint, was ever used on a United States coin. This silver content gives the 1943 nickel an intrinsic metallic value that is significantly higher than its five-cent face value, fluctuating with the market price of silver.
