Or could it be an newer type of red star as replacement to the early version that was lost in combat?
I don't think this is a legit duplicate, but rather a star from the 2.8 - 2.9 million range where they sandblasted the reverse, including the serial number. This is very uncommon for official duplicates, especially since they only partially erased the mint mark. It does have a Cyrillic 'D' and stamped serial number, but I don't trust this piece. Just my two cents.
I would trust Auke's judgement.
Thanks for the reply. I still have much to learn.
