Fantastic !!!

Point well taken. Maybe the 1854 mule of A2? or 1916 patterns, that also appear more often... The issue would be the price -- those coins, maybe not as rare, but more desirable and command a higher price tags. Do you think I should expand the time period? metal?

The given examples in my opinion aren't equivalent on a rarity. I would give an example denezhka 1856 BM (monogram broader) or denezhka 1855 BM (monogram narrower). These coins are more or less identical on a rarity

If it is possible, give some examples of equivalence on a rarity from the period 1850-1917.

That is great information! Now I can determine my two 10kop1762 as from EM and from СПМ

Thank you very much indeed. BTW has the author or anybody else tried to distinguish the copper 5kop1758 (Ekaterinburg or Sestroretsk mints)?

I am very grateful to you
