Russia Perforation Error Information Request

I was looking through Cherrystone auctions and was surprised to see how many perforation errors popped up.
I did a deep dive into my own Russia Space collection and found these two, Sc#s 3022 3023 aluminum lithographed, which are 12½ all around, when Scott says they should be 12½x12.

I used the 2653 Sputnik anniversary as reference because it, among others, were listed in Cherrystone with the same 12½ perf error, but I couldn't find any of these in the 2017 catalogue.

Does anybody have any additional information about these two?

Russia has more "errors" than any other Country. Why? Because Russia figured out one hundred years ago that "errors" mean cash. These have been legitimized due to numerous specialized catalogs assigning values and sellers going along with it. IMO very few aren't deliberate creations plus production standards are loose. As long as the stamps can be separated what difference does 12 vs 12.5 make. Keep producing Comrade!!!!!

The Russian specialised catalogues mention the 2 stamps (1965 Cosmonauts' day) as line perf 12 1/2. No 12 1/2 X 12 variety is mentioned. Regarding the multiple perforation varieties of Soviet stamps, the truth is quite more complicated than the explanation offered by rogdcam.

With the aid of tukhta of course. They're not Stakhanovites!

Are you sure that's accurate? Both the 2017-18 Scott catalogues show the perfs to be 12½x12.

Lol. I think that's giving them waay too much credit. "Never attribute to malice that which is adequately explained by stupidity (or incompetence)".

The CCCP produced an overwhelming amount of design types, and had just as much passion for their abundance in the methods/materials they used to make them. Pretty typical of the autocratic mindset to show off superior capabilities, even through stamps.

If we were to assume they also placed "Easter eggs" in the form of minor technical discrepancies that can only be found under careful examination on top of all that, it would be quite impressive. But I tend to think they simply messed up occasionally. Just makes more sense, all things considered.

Yes, I am sure. This is my collecting field.
Below is the relevant page from the Zagorsky catalogue.

If one wishes to discuss seriously about philately and not with pre-conceived Cold War mentalities, explaining the different perforations on Soviet stamps as results of technical incompetence will not lead you anywhere.

I love vintage Russian stamps and currency - although complicated to learn and research, I think they are all beautiful to look at.
