Question: I recently purchased a Soviet Mother Heroine from the Tbilisi dry bridge market. I did quite a bit of research online prior to purchasing it in an effort to get an authentic one. Nonetheless, I'm still having a hard time being certain because of the reason Chuck mentioned. Everything on the medal seems quite legitimate and authentic. The serial number and size and shape of it look good and the seller had what appeared to be the legitimate documentation. But it's hard to be certain if the star is real gold or a replacement. With that said, after buying the medal I used a powerful magnet to do perform the basic precious metal test. The star and medal in general do not seem to respond to the magnet at all, but the back of the medal moves very slightly in response to the magnet. No strong pull or attraction, but very slight one to the rivets. What were the rivets on an authentic HR made of? Any information is greatly appreciated. Thanks.
