Not sure what is doubled as you didn't state where. Your close up pictures are fuzzy, so no determination can be made, making it impossible for us to even begin to help you
I know a little blur new phone but I wear glasses and I can see the reverse one cent is thick and double
If you put your phone on a solid object, so that there is no movement(Which causes the fuzzy/blurry look), then fill the camera frame with the area(s) in question and use timer or VERY gently use the shutter, you can get better, in focus, pictures,
It could be Machine Doubling(MD)/Strike Doubling, Split Plate Doubling, Die Deterioration Doubling all of which are common and not really classified as errors. For us to be able to assist you we REALLY need decent, in focus, pictures
