I honestly don't have much knowledge when it comes to error coins. Look at the "One Cent." Sorry for the picture. I had to use some magnification to even get a photo that you would be able to see.
Hard to tell from your pic. If it's a die crack the line you see would be raised above the field. It could also be a lamination or just a stain. IDK.
Thank you for the reply. The "crack" does not seem to be raised from what I can see. You can't really tell in the picture, but it seems to be a slightly different color at the 6 o'clock position below the "crack." Thanks again.
