Recently received an
ebay lot that looks to have been mostly comprised of a Russian person's ca. 1991 coin jar. Loads of 1961-1991 1 through 20 kopek coins. I checked for some of the more scarce varieties, and found a 1991 5 kopek with the Leningrad mintmark. NGC does not have this particular variety listed, but I did find a similar coin online for a couple bucks.
Is this anything special, or is it just a fluke that NGC forgot to list it?
