Forgot that I bought the two key bi-metal Russian coins a while ago before the prices of them went out of control. Mintage of both of them are at low 100,000 each which is the lowest of the entire Russian bimetal coins. Bear in mind that most bi-metal coin mintage at around 5 - 10 million, which is by far the lowest mintage. Collectors believed that none of them entered circulation. Chechen: Yamalo-Nenetskiy autonomous okrug As of why the low mintage - who knows, maybe political factors came in play. Nevertheless, beautiful 10 ruble coins. I like them both. Here's another interesting error coin with a different reeded edge. Released recently, this coin has a different reeded edge. North Ossetia Error coin on the right As you may tell, the difference is in the number of reeding - I believe it was 180 versus 300. Not sure why this happened but this is quite interesting. Please show your Russian bi-metal coins too.
The Chechen Republic type (the first one coin) is very rare and expensive. I saw such coin for 155 $ a couple of days ago!
