Probably looks better in person than the pic I'm guessing? (i can only see a little bit of blue toning) You might be able to get a good price for it on ebay. Hard to really put a value on it though, whatever someone is willing to pay......
Need much better pics. Also, the slab looks like a basement graders slab. Based on this image, the coin looks cleaned. Based on NPG coin grading service, it is harshly cleaned. So, no value.
My interpretation is that this is haze (such as PVC haze) and haze is something most folks avoid. Of course, it could be the images.
I see a polished nickel. Do a search for NPG grading and you will quickly see it is nothing more than a faceless, basement slabber who puts cleaned and worn coins into sub-par slabs with MS labels.
