I'm not sure. I just looked in the plates for
RIC and found a
quadrans, used the
Index for the plates which took me to that one, and there, directly preceding it, was the grain ears and poppy, no. 713. Actually, I was more interested in its being copper. I've been told of the small change being struck also outside of
Rome, but for Antoninus I don't know, so I leave it to you.
It's a nice coin, though.
