I don't think we should new year lines, since the star differences can NOT be seen on worn coins. The high or low P certainly, but I still think it's enough just to say that 3 varieties exist?
Hello.
For almost all Soviet coins there are possible variations of the stamps. For stamp hunters your information will be scarce; for ordinary collectors, I think there will be enough comment.
