Set 3 (partial)

Consistency of design and production indicate that these badges were issued in Beijing as part of a "milestones" series or set. The extent or title of the series is unknown; the inclusion of Shaoshan and Gutian preclude it being a Long March set. The differing metallic hues suggest that these seven  badges originated in at leat two different sets; it was fairly common practise to issue the same set or series in  both gold and silver finishes.
