My advice is that if you truly believe that these cents are made from anything other than a .950 copper alloy, please have them authenticated by a professional with expertise in such matters.
That being said, the lighting and focus on your images is so poor that nothing can even be guessed. There is, however, no record of any 1941 cents being made of anything but .950 copper.
There are likely hundreds of thousands of cents from that era (pre WWII) that were plated with zinc in high school and junior high chemistry classes. Are the coins plated or are they a white metal throughout?
