Speaking of russian coins. If it is not in the major catalog (Uzdenikov, Bitkin, Usupov, Duke etc) chances are the thing is a coin - waaaay less then 1%. Major discovery in the archives have to be made or some big collection with the prooven history appiers on the auction or in the museum. Otherwise it is just a modern junk.
I think I will politely disagree with this. The modern references named essentially use the
Grand Duke as amplified by Giel-Ilyin and Ilyin-Tolstoy. In each case the modern author
has made a good effort to add pieces to his lists but there are still many discoveries waiting
to be found.
A reasonable example of this is the 1786 gold two roubles. It was originally published in the
late 1830s by Chaudoir but then denounced by Schubert in the 1850s and again by the Grand
Duke in the corpus volume for Catherine II. Giel, Ilyin, and Tolstoy unanimously condemned
the Chaudoir listing, saying in essence that it was a die fault, not a 6 in the date. We now know
a great deal more about dies and hubs than was known before 1917 and the 1786 two roubles
is genuine beyond any doubt; it is, however, not listed in any of the references given above.
It is not necessary to find archival documents or provenance to a major collection to show that
a coin is genuine. I will agree with And986, however, that such proof is welcome at any time.
