Help Identifying 2015 Jefferson Nickel 0

Going through my change jar and found this nickel that caught my eye. I am not very verse in numismatics terminology, but it appears to me to have maybe a satin finish or matte finish. I have tried looking up either of those finishes for this year and mm to no avail. Could someone give guidance on this coin? Or is it just toning that is occurring? 

The top coin is the one in question. The bottom coin is shown for comparison. Both are from same year and mm.

Also to add, sorry about some of the glare. Best I can do until I figure out my lighting situation.

There was only one finish on a 2015D nickel so it can't be a matte or satin finish.

I would say it is probably toning.

The top one was struck from fresh dies and has toned.

Yes, correct, however I might have a different view if it were between 2006 and 2010.

Thanks. When researching that is all I was seeing also was this year only done in one finish. I guess it was throwing me because the conformity of the toning all the way around.
