CCCP Soviet Union Communist Cold War Era Enamel Pin Lot 60’s 70’s Expo Olympics. 15 metal enamel pinback lot, note the missing back pin bar on the blue and red pin showing a castle. I think the Lenin 1870 to 1970 is silver (not 925 but in the 800’s, I’ve seen it described that way but I can’t read the markings on the back). — See photos for condition details. — I don’t have a way to arrange for a local pick-up of this item, I’m sorry for the inconvenience.
