10-ruble coins.

In total, 64 coins were issued (with a face value of ten rubles), although I'm not a numismatist, but I know this fact.

Maybe they did issue 64 coins, but we are only considering coins that are NOT made of precious metals, and they are all here. There are already 48 of them.

I came across a Vladimir coin from 2008 - I'm adding it to the list.
And now there are 48 coins.
