It's a very common and understandable question, as the history of nickels during the World War II era can be quite confusing. You've hit upon a key detail that distinguishes valuable silver "war nickels" from their standard counterparts.
Rest assured, a 1941 nickel with no mint mark is not a silver coin. The composition for all nickels minted in 1941, whether from the Philadelphia mint (no mint mark), Denver (D), or San Francisco (S), is the standard alloy of 75% copper and 25% nickel.
The United States only began producing silver nickels in 1942. As World War II intensified, nickel became a critical material for the war effort, particularly for armor plating. To conserve this vital metal, the U.S. Mint changed the coin's composition to a blend of 56% copper, 35% silver, and 9% manganese. This change, however, did not occur until partway through 1942 and continued only until 1945. Therefore, your 1941 coin just missed the window for that special silver composition.
So, while your 1941 Philadelphia nickel is a fascinating piece of pre-war American history, it does not contain any silver. You'll want to look for nickels dated between 1942 and 1945 with a large mint mark above Monticello on the reverse to find the celebrated silver war nickels.
