The Serdica mint used the Greek letters KA rather than Latin XXI however, this coin instead has the single Greek letter Δ in the exergue. The attribution to a first phase of the third emission at Serdica is undetermined, however, Probuscoins.fr cites parallel issue with the same reverse type which is confirmed as the second phase of the third emission as evidence for this attribution. This initial phase is unpublished by Pink or Gysen and is extremely rare.
Sol's presence on coinage experience a revival under Probus after falling out of favour after Aurelian's death in 275. Probus used a variety of Sol reverse types but this facing quadriga type is exceptional for its artistry.
