8 WWI US Army Infantry Collar Disks US nice Vintage WWl Lot For Sale

Please see all the pictures for details of the exact 8 collar disks you would receive.

My notes read WWI enlisted man's collar disks. 2 read US, 2 have the crossing rifles,1 reads US1, 1 reads US49, 1 reads US MINN, and 1 reads US 125 WIS. One of the rifles collar disc is a bit rusty and also missing the back round nut. I can only find markings on the back of the one disk. It reads possibly The H.A Kal Mich.

Thank you
