WWI era U.S. MARINE CORPS campaign hat

Incredible find. WWI Army campaign hats turn up quite often, and depending on condition, run between $45 -$125 dollars. Army campaign hats have a set of 5 rows of stitching around the brim of the visor. U.S. MARINE CORPS campaign hats are very hard to find, as they only have 2 rows of stitching around the brim.
I jumped on this at a $55 dollar "BUY IT NOW" auction. ...it's well worth $350-$500 ........
