1700 Halfpenny - Date Error And More

I instead of 1 in the date. The only I instead of 1 in the date that I can see clearly was in the Nicholson collection, but that example also had the I/V, whereas this coin does not appear to have that and the date placement is different. What is also interesting about this example is the additional error in the hair of William III. There is a line of teeth (from the toothed edge / denticals?) in the center of William's head! I have been unable to find another with this error.
