Aluminum, paint, lacquer, 47.4 x 30.9 mm. The reverse shows raised maker mark САЗ ("SAZ"). For unknown reasons, this badge is much more scarce than the similar 50th and 60th anniversary badges. In excellent condition.

Despite its relatively humble appearance, this is definitely an official badge, not a souvenir. Commemorative badges of this type were awarded to various low ranking employees within KGB and its many axillaries - as opposed to the higher ranking badges in brass awarded exclusively to active duty KGB officers. Some of the aluminum badges were probably also given to KGB retirees.
