"Cloud Kopecks" (1 Kopeck 1755-1757 and 5 Kopecks 1755-1761 ) [solved]

What is the story behind these coins?
I noticed that they look weird when I saw one at a shop.

Atleast some of them are countermarked, but are all?

Here is one possibly countermarked on https://en.numista.com/catalogue/pieces91196.html :




Help is appreciated. thanks

hello,

yes, lots of these kopeks (about 1/3) were minted on 5 kopeks which were demonetized and bought from the people to mint new coins. There is an opinion that such barocco design was created to hide a picture from an old coin.
