Thanks for your concerns.
- I believe because similar cases with UAE, Qatar and Kuwait I've dealt with before resulted in getting the wrong year lines deleted after researching and checking with others.
- There isn't a specialized catalog I'm aware of. Krause lacks latest years and have no info about 1st/2nd types, magnetic and non-magnetic, so it's way behind (at least in its 2016 version, haven't seen the 2017 one)
However, a very good website (owner is a member here I believe, and we have permission to use its pix) have all years listed with pix of each year

- The extra year in the 100 & 25 fils are listed in Krause so that's where they came from. The 3 year lines in the 10 fils are listed in Krause along other year lines as a 1 type, and hence listed on Numista. Later on different types where discovered and new pages were created but these year lines were not deleted off the 1st page, and that's why they exist.
- As for owners: for the year in the 100 fils coin; "15 members" only own that year; against an average of 250 members for the other year lines.
- "10 members" only own that year; against an average of 200 members for the other year lines.
- The 3 year lines for the 10 fils: about 35 each against an average of 200 for the other ones
- Searching for pix on google, couldn't find anything for these 5 year lines
- And lastly, I can only see number of owners for each year, but can't see their names
