Every so often I see where someone as a question about a goldish colored penny usually from 1944 45. I've seen a couple answers to questions about the pennies. I've heard that they are a different metal composition with high level of zinc, and then I've heard they are a solid zinc planchette which is plated in copper, those are the two reasonings I hear the most it's been awhile since I've seen someone ask. I got a few of these, all 1944 Philadelphia cents, maybe a 45 as well but predominantly 1944. Can anyone give an accurate answer as to the true reason for the color.
