Wondering if any one can give me any info on a penny I found in w/ my great grandfathers WW1 memorobelia. It is a 1920 Wheat Back that is silver in color. The composistion is not really similar to the steel pennies I have from WW11. To be honest, although I don't know that they did this, it almost seems to be actual silver. The coin itself is in good shape (relatively little wear) Some kind of error? I can't find any info on this one. Any help is appreciated. I'd take a picture but my camera is non functioning.
