MSG-D Marine Security Guard Detachment Dublin, Ireland 241st Bday Challenge Coin

  
His Challenge Coin is from the USMC Marine Security Guard Detachment stationed at the American Embassy in Dublin, Ireland. This coin is from the 241st Birthday Ball held in 2016.

This coin is numbered as 000. I realize the numbering doesn't make sense but it is what it is. The dimensions are 2" x 2" and weighs 2.0 oz.
