If all three photos are of the same coin, there is something very drastically wrong with your lighting setup or your USB camera or both. I suspect the camera software, filling in the extra pixels to try and make the photo look focused. You might search for other usb camera software that can stack shots and produce a more honest ( the photo ) representation.Look on the astronomy or 'macrophotography' sites.
Thank you. No pictures were touched and there is no reason to do so sorry and its straight from a camra phone same as all the pictures. Some were sent to my computer from phone but not these pictures.
