For me, it is easiest to compare the clashes between the wreath and the eagle. Because the E has clashed one more time than the D, it is most obvious there. The difference in strike quality and wear in lower grades makes it difficult to tell the difference.

Would need a pic of the obverse neck clash because that is the difference between the two.
It also appears the right wing clash below n has two lines vs one due to die rotation.

So I think yours is an E.
