That imge is about the best I can do, I know nothing about photography and am waiting for a macro lens for may camera. I'll try to describe what going on with the coin. There is a crack (line) from the lower right corner of the building to the rim of the coin. From where it meets the building it widens up to the 1st step. From there it looks like a post. The funny thing is that you can see the ridges of the steps. I was thinking that if it were split plating that the steps wouldn't be seen over the post.
