We really, really need help here reading posts and us having absolutely no idea of what the poster wants to know. We are not mind readers! What is it that you want to know? Meet us halfway and tell us what exactly you see going on with your coin and then show us through close ups of those areas. "What is it called"? Doesn't help us. Help us help you, describe what you see and where you see it. Thank you.
