Design is much the same as last year, not enough that there would be rule changes in what to look for.
First, the thin line above and to the right of the statue isn't enough to confirm or deny hub doubling. Basically, if it is anything, it's too minor to list.
On the other side of the same column, you have a stain on the coin - nothing else.
The other columns, ceiling, and steps are normal.
The 8 on the other side of the coin looks completely normal, I'm unsure of what you are trying to point out.
