For some unknown reason this coin is still less expensive in Russia that overseas (ebay in particular)... I was lucky to purchase one on local coin bazaar for around $6 in XF condition during my trip to Central Russia late December...
That is an interesting observation.
Could it be that this price inversion on the USSR polkopek is because the early non-silver Soviet business strikes (i.e. the copper coins) are more easily found in Russia than in the West?
When I first saw Uzdenikov's book (1985 first edition), I was puzzled by some of his rarity ratings. For example, Peter I gold 2 roubles coins were typically rated as very rare to extremely rare, yet they seemed to appear for sale in Western auctions fairly regularly.
And some copper coins (like the 1714-НДД kopek) were rated as merely scarce, yet I would almost never see this coin offered for sale despite my searching for it (even Brekke did not have this coin in his collection).
My speculation is that Uzdenikov's rarity ratings were based on what could be found in the USSR, while my perceptions of rarity were based on what I saw in the West.
Given the war and chaos in Russia after 1917, it seems to me that those Russians fleeing to the West, perhaps leaving under emergency conditions, would not be able to take everything with them. If taking a coin collection, it seems reasonable that collectors might take their gold coins while leaving behind their bulkier copper coins (unless the copper coins were rarities).
So, gold coins might mostly end up in the West, while less intrinsically valuable items (like the 1714-НДД kopek) might mostly be left behind, creating very different impressions of rarity depending on whether you were inside or outside Soviet territory.
Of course, I might be wrong and I have no proof that this is what happened, but it seems like a reasonable explanation to me.
