Hello
I ask for changes on the page of this coin.
1) Year "1980 ЛМД Leningrad Mint" does not exist - there is only the proof variant.
2) Mintage of 1982 ЛМД Leningrad Mint is 28 000 pieces.
Here is the link to special WEB page dealing with Russian coins - unfortunately only in Czech language. The source listed here is the National Bank of Russia: http://www.ruske-mince.cz/katalog/sssr/mince-sssr/mince-sssr-1961-1991.php
Coinage list for all variants seems to be correct.
Thanks
