A Single, Original WW1 Pennsylvania National Guard Keystone Collar Disk for Company G of the 6th Infantry Regiment. The Disk is constructed of darkened Bronze and is missing its screwback. The disk is 1-1/16" in height and would complement a pre-WW1 Uniform perfectly! Overall, a nice early Pennsylvania National Guard Collar Disk in VF+ Condition! Winning Bidder to add $3.00 for postage, insurance is extra, if desired. Good Luck and Happy Bidding!!!
