Italian states (Lucca), KM#A34

The catalog states that the only date for the coin is 1826, but the very picture on the coin's page https://en.numista.com/catalogue/pieces22613.html
has 1841 for the date. I coin I have is dated 1841 as well.

Could it be a mistake in the catalog?  

Thanks in advance.

It very well could be. Can you post a picture?

I am not very good in posting the photos  
But there is the photo on the following sites:

and here

The 1826 is KM#A34 and the 1841 is KM#34a. So it looks as if the photo posted in the Numista Catalog is for the 34a, but the rest of the entry is correct for the KM#A34.

Does it mean that for the coin to appear somebody has to add it to the catalog?

Yes.

I will make the coin and post link after I'm done.

Can anyone provide a picture for the 1826 version of this coin? https://en.numista.com/catalogue/pieces22613.html
