I found this cool U.S Marine Corps button/ cuff link however I have no idea as its age. It was found at a site that dates from the 1880's. I would greatly appreciate ANY information on this button and a possible age. Many Thanks!

Its a button off of a WWII USMC HBT (herringbone twill) fatigue shirt.

Just kidding - your moniker is a giveaway - nice concise, precise ID
