This coin is a TB/TB example. Even though the reverse teeth have a somewhat rounded appearance, they are indeed toothed in reality. On a real BB example the beads are closer to the inner ring, not the outer rim. There is also a differance in the Bead count, though I don't recall what it is. Every coin dealer here in the US has a example like yours marked as a Mule, which is incorrect. I have a example I purchased from Michael Freeman on my website, if you care to see a authentic example.
