It looks like that there are two slightly different obveres of this coin. One where the head of the emperor splits the obverse legend (DIVVS ANTONINVS) and one with continuous legend. The coin on the Numista page is the first type but yours is the second. Check the examples on the first link, I think those are closer ones.
