Looking for some help on my 1786 Baby Head electro

I showed it in my exhibit at EAC Philly and the prevailing thought is it is a copy of the Bennington example, but I can't explain the apparent differences as shown in the combo images of both (Bennington images on the right).
Since I have been told there are no other high grade Baby Heads out there the Bennington example is the only plausible candidate despite the differences- any other thoughts appreciated!
The 1st image is of my example, the next images are this one as compared to the Bennington piece (apparent differences marked).
Any help from anyone who has seen or has knowledge of my example appreciated!

Doesn't look like it was the host coin.
Just because there's no other high grade example known now doesn't mean one isn't out there unknown in hiding.
Your coin was copied from a high grade genuine Baby Head as the dies match. If the Bennington is the only one, than that's the model. Otherwise there is another with the exact same amount of wear.
