Cell Phones (iPhone or Android): First, do not upload cell phone pictures of screens. They are terrible. Please check your camera settings are set to Medium quality. If it uses compression use 70%, it's perfectly fine for the internet. For file type please use WEBP if your phone has it, otherwise JPG. Avoid PNG and GIF, they are horrible choices.
Be sure to crop the image to only show the coin. This is a great setup for cell phones.
If needed you can use the
