I think "prooflike" is a better description for the coins that were issued in the sets at the time. Proof applied more to the Olympic coins.
I remember writing to the Bank of Foreign Trade of the USSR at the time for these, and never getting a response.
Agreed. Under magnification the fields of the coins in the sets are not proof but proof-like. There are tiny imperfections easily seen under a glass; without using a glass they do appear to be proofs, however. On the other hand, the true proofs (including the special Olympic copper-nickel pieces issues in the blue cases) are fully equivalent to proof coins issued by other world mints.
When I was at the Mezhnumizmatika office/store in Moscow in 1973 I asked about the quality and they indicated that they did not consider the sets to be proofs. They certainly did not advertise them as such in the literature they sent me each year listing sets for sale.
I consider the annual Soviet mint sets to be roughly equivalent to the Special Mint Sets issued in the 1960s by the U.S. Mint.
