Strange instription in the USSR sector [solved]

At any part of the USSR coins such as
https://en.numista.com/catalogue/ancienne_urss-1.html

there is a statement:
100 kopeyki = 1 ruble

Maybe it is worth to correct it
100 kopecks = 1 ruble

?

This line is not in Russian:
100 копеек = 1 рубль
it is not a transliteration of the correct Russian phrase in English:
100 kopeek=1rubl'
It is just a fantasy.

Agree, "kopecks" is a proper word here.
