I started wondering how am I supposed to choose a random coin in my collection.
I idly opened the Numista main page. It had a slideshow of random coin types.
Most of the time, the coins shown are either very common types or something that I don't have yet. (Often they're both.)
This time, the
very first coin I saw was one I knew I had.
More importantly,
I knew where it was, which is actually pretty rare for my collection. Usually I just look all over the place for a while.
(It was also the very first coin I ended up taking out of that box when searching, which I decided was
yet another sign that I should use it.)

Russia, 10 rubles, 2013-MMD, commemorating the 20th anniversary of the Russian constitution.
Numista 53089. No idea if it's in Krause yet.
Points:
- 1 point for a commemorative coin
- 1 point for a coin about a constitution (of any country or other entity; probably will be commemorative)
- 1 point for a coin about a 20th anniversary (of any event; probably will be commemorative)
- 1 point for a Russian coin (any Russian predecessors or subdivisions count)
- 1 point for a coin denominated 10 (of any monetary unit)
- 0.5 points for a coin denominated in rubles (of any country, not necessarily Russia)
- 0.5 points for a coin from Moscow mint (for any country, not necessarily Russia)
- 0.5 points for a coin from 2008-2018
- 0.5 points for a coin from 2013 (in addition to the above)
All of the above stack, so the maximum is 7 for an exact match.
...I suspect that any collector of Russian 10 ruble commemoratives will probably have either an exact match, or at least another high-scoring entry.
Of course, it's not like CCF has particularly many collectors of Russian 10 ruble commemoratives...
