At the beginning it was considered as a mistake in description. But it is a miracle.
Let's consider almost any coin from Isle of Man. To be precise let us show the miracle on 2 pence of the type 1980-1983 https://en.numista.com/catalogue/pieces9856.html
The lettering of both sides described some fantasy, that is why the modification request was created (https://en.numista.com/catalogue/contributions/voir_demande.php?id=2194328 the link is active for numista team only):

Obverse (head): Lettering ISLE OF MAN ELIZABETH II PM 1981
Reverse (back): Lettering 2 AA
As you can see the modification clearly indicated the readable symbols on the photos of the coin, which are present in the article.
Then the modification was approved
and this is the result:

As we can see the lettering now is
Obverse Lettering:
ISLE OF MAN ELIZABETH II
1981
Reverse Lettering: 2
Again it does not describe any real coin anymore. What we got? The Numista catalog intensionally supplies the readers with fake!
The same trick happened with any other coin modification, for example https://en.numista.com/catalogue/contributions/voir_demande.php?id=2194334 for
https://en.numista.com/catalogue/pieces10211.html
and these are not the only demonstrations, many previous requests for the Isle of Man coinage ended with the same miracle: the lettering sections describe anything but not the real coin, pushing the reader to conclude that it is item in his hands, that is a fake, the reader does not have a coin.
Question. How the program developers permit these fakes be present permanently in the catalog?
