1847 Half Dime-Grade, Authenticity

Hi,

Please look at this coin considering that the weight is 1.33 g, the diameter is 15.23 g, ans a rotation of 45 degrees exists.

I also included a view of the reeded rim.

From my perspective it appears that the ridges are slightly slanted with alternating humps and ridges.

It is hard to photograph this reeded edge to accurately convey via a digital photo the true condition.

I personally did not find any variety applicable to this coin so speak out if you feel I missed something.

Finally, I need the grade and if you feel that the coin is authentic.

Thanks,
