This coin has an unlisted workshop, RIC only lists the first workshop (out of 4 known) for this issue. It was sold as Arles 185 and it is identical except for the altar. Arles 185 has a plain altar while 188 has a decorated altar. I am not sure if this is actually merits a separate RIC number, but it has one.
