Hi all, I've posted this coin with a group of others from my grandfather's collection he left to me and I've found and researched many of them, but this particular coin I just can't seem to find any information about. If there's anyone who can help me to pinpoint the region of this coin and the background it would be very appreciated. Thanks again to all and thank to the Armed Forces for your service.

Hi all, these are some of the coins I've accumulated over the years and being a beginner to collecting and a member how do I go by getting certain coins graded, thanks again for your help.(These are just a few to get posted)
