I have a theory, but only someone who has some access to the pre 1840's equipment can prove it.
I would say that having a special punch for every Russian character is expensive. A lot of characters have similarities Ь Б Ы, a lot are parallel bars with some line in between. I would say that they just made punches for common elements and then added bars to change character values on dies. Sometimes the die cutter messed up and forgot them or added them in the wrong in the wrong place.
I would generally agree with the following exceptions:
1) St. Petersburg engravers were using whole letter punches for medal dies as early as the
1740s yet continued to do ‘piece lettering’ for coinage dies until 1844/45. (By piece lettering I
mean that the letter A was made up of /, \, and – as well as small serif punches.) Most European
mints had switched over to whole letter punches in the 18th century.
2) A few Russian coinage dies appear to have used whole letter punches prior to 1844; the lettering
on the Borodino commemoratives of 1839 is so well done that it is difficult to determine if whole letters
were used.
3) The copper mints under Catherine II definitely used piece lettering. I have a KM piatak in which the
letter E in KOPECK appears as an F, the engraver forgetting the lower bar.
4) There is no doubt that letter variations were used during the 1750s and 1760s to distinguish one die
from another, for security purposes within the St. Petersburg and Moscow Mints. The letter C, for example,
often appeared as a G at Moscow for just this reason. There is also good reason to believe that P (i.e Pi)
had the top bar left off as die identification; it also seems to have been done in the case of pattern coins
on occasion. The 1762 two kopecks mentioned by Steve Moulding is puzzling, however, and does not
seem to fit any particular rule.
5) On the other hand, it is my opinion that mistakes during the 19th century were just that and not deliberate.
It may be that poorly educated or illiterate die-sinkers were employed to save money.
6) After 1844, when full hubs and whole letter punches were used, I know of only one spelling error, on an
1851 quarter rouble.
