1977 Half Error (Update:magicians coin)

Not that I ever keep these things but, while searching tonight I came across a weird find. I half that had a hollow ring to it.
While looking at it I noticed the reverse rotation of about 70%. The eagles head is in the 7-8 o'clock position.
Now I just have to search and see what this thing really is....
Everything else looks normal.
