Part of the problem is that you are using screen shots which are not supposed to be used on this site.
They are too pixilated to give a clear image of your coin.

This topic has been locked for pictures of a screen. These are almost always terrible and against the rules. We are locking this topic to prevent posts with "We need better images". You will get many more quality responses when there are quality images in the first post of a topic. Please start a new topic when you can upload non-screen pictures. If needed, you can use the testing forum. When you start a new topic this one may be removed. So don't panic if you get an email that your topic was removed; it's only this one.
