@medved, by clicking on your pictures, I was able to blow them up enough to see mostly what you are talking about. For the 10 Kopek, I'm not sure what to call that section of rim that was not properly struck up as I haven't seen that before. It seems to be some sort of collar issue, but someone else will need to weigh in. The first 20 Kopek coin had a little grease in the die when the coin was struck and this prevented the metal from flowing into the first letter C of CCCP. This grease-filled die error is more valuable when more of the design is missing. The second 20 Kopek coin had a big glob of something between the die and the planchet when this coin was struck. This is another struck-through error and nicely distinct. I can't speak to how common this is with coins of the USSR. For your ruble with the engraving error in numbering, this seems to be well known, for example on numista: https://en.numista.com/catalogue/pieces90211.html Again, I'm not sure how common this might be. Overall, you have some neat coins. "If you climb a good tree, you get a push."

Thank you for the answer, I know everything about this types of errors and how common they are. I don't need a tutorial :-)
I'm just asking for English translations of these errors, for example like: "double die", "die crack", etc

First one looks like a clipped planchet.
Middle two are some type of struck-through.
Last one is an engraving error or some type of design variation.

@tanman, just askin'--have you ever seen a clipped planchet where the only thing that is affected is the strike up of the rim? I haven't. Could it be some sort of collar error? I don't know...

Yes, although these minor ones are sometimes called rim clips.
You can see the Blakesley Effect on the opposite side of OP's coin.

Once again collegaues. I found this article, so...
Types Of Clipped Planchet Error Coins
Clipped planchets represent a separate type of error coin. But those who collect clipped planchets recognize these 4 distinct types:
Straight-edge clips — There's a straight edge on the coin where it was mis-cut.
Curved clips — Due to a crescent-shaped area of missing metal, the coin has a concave curve-shaped edge.
Irregular clips — The trailing edge of the metal strip appears ragged, giving the coin an irregular edge.
Bowtie clips — There are 2 curved clips on opposite sides of the same clipped coin, creating the appearance of a bowtie. a most unusual type of error.
More specifically, these are the 4 possible outcomes — an explanation of each of the 4 types of clipped planchet error coins:
Straight-edge clips — These feature a straight edge on one side of the coin.
Curved clips — The error here is a crescent-shaped miscut on either one or two sides of the coin.
Irregular clips — An irregular clip shows the straight-ish but ragged edge unfinished leading or trailing end of the sheet of metal from which the blank is cut.
Bowtie clips — These boast 2 curved clips on opposite ends of the coin.
So which type is mine? :-) if we talking about 10 copecks 1988?

I know it doesn't look especially curved, but I believe yours is likely a curved clip.
The shape of a clip that small would be easily misshapen by the pressures of striking. The planchet being struck would flatten the curve a bit. Curved clips also seem to be the most common, in the US at the very least.
