We can solve the mystery. Just post closer pictures of the bottom two, like you did with the close-up one.
You want me to tell you what I think? Okay, I think picture sucks. You took this picture, didn't you? You need to take two more just like it from the other two coins.
No, I downloaded that image. I'll have some close up shots of the device posted shortly. I've just taken some this morning but I need to transfer them from the camera to my computer..
Okay, let's start over. Maybe I missed something. First question, it's an easy one. Is this your coin?
