WCO,
I understand your point but will have to disagree to some extent. The coin you use to illustrate your point has very heavy die polish. It is the polishing that has cause the thinning and separation. Note the heavy north-south die polish lines on the reverse - not uncommon for some proof coinage. So, the separation is not a strike issue, but rather a reduction of the devices due to die polishing. The coin is quite fully struck as evidenced by the rim, dentils, etc. that were not affected by the die polishing. In sum, if one sees separation in the devices but no die polish lines it would be suspcious.
Also, the coin in the blow-ups does not appear to match the one in the slab. Specifically I note the heavy "carbon-spotting" particularly those near the bust's temple - ?????
Dear rittenhouse,
You confirmed what I was saying from the beginning that it is heavy die polishing on Proofs. Unfortunately, it was in another thread so that is why you missed half of the discussion, one person there reminded me not to post in "his thread".
I said exactly the following:

Another problem on Proofs is that ... low relief details (on coin) are polished off on a die. For example on 1859 Commemorative Rubles sometimes horse's upper legs seems to be away from the horse and eagle flies above the helmet. I used to see more dramatic examples on other coins. Some "numismatists" on Russian forums were saying those are fakes because "... a proof should be perfectly struck"...

I uploaded new somewhat better picture of coin in the slab (click old link #3), I hope this will tell you it is the same coin. I sent it for grading mysef. Pictures in a slab were made by low resolution old camera and are not that good but I hope the coin is easily recognizable.
Cheburgen, I do not want "to waste my time" but I am very disappointed with processes going on many Russian forums. Absolutely perfect and authentic coins are called fakes (see what Timofei and several others said), collectors are afraid to buy them in Russia just because of large group of "knowledgeable authorities" made up "public opinion". On the other side fakes are easily sold and in quantities... same group of "authorities" calls them authentic and advises to buy. At first I thought it's just mass luck of knowledge in Russia, but I am not so sure anymore. Seems like many people there are playing game of "...we'd rather sell fakes...". I was reading Russian forums about your 1859 Commemorative Ruble where hoard of "authorities" gave a verdict of your coin to be a "... 100% fake".
GHV,
About PL vs Non PL Business Strike coins anyone can tell if he knows how to do so. You do not need me or making pictures for that. PL is just measure of reflectivity of surfaces of MS coin, there is a way to "measure" it.
