I just checked a relatively recent Scott catalog (2017), and they do not list anything for Comoro Islands after 2009. There is no statement explaining why they stopped listing.
I checked this website: https://stamperija.eu/#search?q=comoros Y&T 247 Michel 2651 Jacques (jlav)
Thank you very much for the valuable information. On the sheet it is mentioned "2010" as year of issue, I searched on 2010 stamps. Is this normalto be catalogued 2009 ?
foudutimbre, They are listed as 2010 on the website; I believe Philatarium was just referring to the fact that none were listed after 2009 in his particular catalog.
On Jacques Indications, I have checked on the Yvert caalogue and the sheet is effectively catalogued in 2009. I understand if the stamp/sheet is catalogued a year after its issue but the reverse ????
In that case, in does indeed seem quite odd!
