Hello,
There are incorrect denominations in Russian for the coins of Russian Empire, Siberia and possibly some other.
Some examples:
Value 10 Kopecks (10 Копейки) (0.10) - shall be 10 Kopecks (10 Копеек) (0.10)
5 Kopecks (5 Копейки) (0.05) shall also be 5 копеек
I beleive there may be plenty of other mistakes, so possibly it is better to see and check the whole list
