In brass, 32.1 mm wide. Shows the Roman numeral "X" on the obverse, the distinguishing feature of KGB long service medals.

In outstanding, excellent condition. The raised details are perfect and crisp. There are only a couple of tiny dings to the raised edge, nearly unnoticeable, with no other wear. The gilt finish is exceptionally well-preserved and bright, showing no blemishes or tarnish. The ribbon is old but immaculately clean. The connecting link appears to be of the period.
