An interesting Antonius Pius ancient not in the catalog?

I also picked this up from the same place as where I bought the Maximianus coin mentioned in another post.

Weight is ~10.75g,

Size ~25.5-27mm

Obverse reads: ANTONINUS AVG PIUS (POTEF?) COS IIII

Reverse reads: S (with a standing figure holding harp and wreath) C

If the coin had a mintmark, it is off flan and not able to be determined.

It's in the catalog: N#261136

The splitting of the obverse text is a little bit different on yours than the one that I've linked, but there are other examples at OCRE, with the same splitting: https://numismatics.org/ocre/id/ric.3.ant.824A
