Without a doubt, the unissued Iraqi 100 Fils 1955 is one of the rarest coins in the Iraqi series. An unissued coin, with very few that actually escaped into the collector market (reportedly 1,000,000 pieces were mint but some experts “guesstimate” about 40 pieces to be in private hands today). The coin, even though dated 1955, carries the same characteristics as its 1953 counterpart. Contrastingly, the 20 and 50 Fils coins of 1955 are entirely different and carry a new design featuring two palm branches under the denomination.
As it turns out, there are also two additional varieties of this elusive coin, besides the one described above. The first of these is the proof strike of the above-mentioned coins. A difficult coin to find, with an unknown but certainly low mintage. The second, however, is something that only became known to me a few months ago when I received my copy of Mr. Ahmad Ghazi Al-Samariee’s book:
The coin appears to be a 100 Fils 1955, but with the palm branches under the denomination. I have never seen one for sale, and nor have I heard of one in private hands. Anyone with more information is encouraged to share their knowledge. Pictures are also most welcome. (July 2014 update: despite diligently trying to find more information, not a single other reference to this coin was found, including discussions with the Royal Mint. Therefore, I personally question the existence of the actual coin/pattern outside of the digital world.)
All three varieties are illustrated below.
