The coins with 5 and 6 full steps at building are known. It is clearly described already by the Numista catalog:
1938 thru 1989 = 5 full steps at building. 1990 to date = 6 full steps.
Due to recent discovery of course this statement is completely wrong. As the result the modification https://en.numista.com/catalogue/contributions/voir_demande.php?id=2090936 was supplied:
1938 through 1989 = 5 full steps at building. 1941, 1990 to date = 6 full steps.
The reaction of a referee looks at least strange:

Despite of the fact described in the source section:
--
Source: This coin is widely known for years and it is strange, that the catalog keeps silence about it.
Take any resource, such as

--
the referee made the rejection with Comment: Too trivial .
Well there are some reasons for this actions, such as:
- desire to humiliate people who made the discovery;
- desire to keep the information in secret out of the users;
- laziness to check the data, which are recognized by the Numismatic societies of the USA;
- or just lack of numismatic knowledge which was already demonstrated by this very referee in his rejections made in the same strange way, for example, have a look at a prominent stupidness https://en.numista.com/forum/topic61551.html
Leaving this next strange incident to the personal biography of the referee, there is still a question:
- how to add the discovery coin into Numista catalog?
