2011-D Grant Dollar Gold Plated? Position A

I think this may be one of those gold plated dollars. Super shiny which has made it nearly impossible for pictures taking, but I hope you all can help me out.

I say gold plated because:
1. is to crazy shiny
2. Excellent in details - like barely showing no wer down on any of the devices.
3. It has a few nicks in where you can see under the plating, but it is silver/grayish looking (not sure if that should be or not)
4. The coloring compared to the other normal dollars, well it doesn't match hopefully you can see the difference well enough from my pictures.

I put it up against my 14K gold necklace for comparison and it is a good match both in coloring and shinyness (if that is even a word).

Anyways I have spent most the day trying to figure this out and get pictures. Kinda silly because it is probably only worth a couple of buck - but just to find this from vending machine change would be a cool story to go along with the coin.

I just can't figure out how to determine if it is or isn't. who know these day it may even be a fake (though I hope not)

Please let me know your thoughts.
