Vintage Amico US Army Eagle Insignia Pin On Chain with Additional Pin (damaged)

A vintage Amico US Army eagle insignia pin on chain, featuring a classic design representative of military service.

Condition: Used with marks, dings, wear, age, and build up. Pin on the right has damage around the blue half circle in the dark area (looks liked cracked enamel). Unknown alloys on both pins + chain, unknown blue stone or color on the right pin. Appears to have the AMICO eagle logo on rear of left pin, nothing on right. Clasps are functional and tested, but not perfectly aligned / bent.
