Theoretically the coin can be listed as RIC 154 as Nero.imp correctly indicated.
However, in fact RIC 154 is a mistake because most variants listed in RIC under no. 154 do not exist in reality. The coin shown in this post is probably the first example of a RIC 154 which I have ever seen even though RIC 154 supposedly is a common coin with "C" as rarity grade!
In reality, the coin shown here is likely an unicum and clearly is a hybrid of different emmissions, i.e. not a coin of a regular issue, as RIC 154 could erroneously suggest.
