1848 Large Date Half Dime-Grade Etc

Hi,

The weight is 1.29 g and the diameter is 15.22 g.

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.

This rim, however, appears to be somewhat different compared to another rim of an 1847 Half Dime I recently posted earlier this morning. You be the judge.

Opine on whether or not any variety applicable to this coin exits.

Finally, I need the grade and confirmation that this coin is authentic.

Thanks,
