The rating is RR is not extraordinary but it seems that it high because the major museums
were willing to have this
type in their
collections. The cataloge cgb gives the following
information:
Pour ce
type, M.
Crawford a relevé une estimation inférieure à trente dies de droit et inférieure à trente-trois coins de
revers. Pour ce
type, d’après M.
Crawford, un unique exemplaire figurait dans le trésor d’
Aquileia. Ce denier est infiniment plus
rare que ne le laissent supposer les ouvrages de référence.
Translation:
For this
type M.
Crawford gives an estimation lower than 30 coins for the
obverse and 33 dies for the
reverse. According to M.
Crawford, only one coin of this kind
type was found in the Aqileia treasure. This
type is much more
rare than one can conclude from the reference edition.
The last sentence seems to justify the high estimate given by the
catalog.
Another example one can see here:

Wildwinds also has an example of this
type.
I also think that the image of
Julius Caesar on coins of this
type is quite interesting (and not ugly as on many coins of
his epoch).
