12/25 year ss service medal miniature stickpin

12/25 year ss service medal miniature. Very rare 10mm miniature with higher grade SS service medal design. Remains in poorly stored condition with some oxidation and missing finish. Was most likely stored in a damp location. The front still shows some good shine with a somewhat gold/silvery look with the edges showing a more silver appearance as does the pin. Even in this condition a very rare stickpin!
