Note: The reverse legend should be PAX AVGG. Strangely, this obvious legend error occurred on at least six different dies. Curtis Clay has said: "The Eauze Hoard contained no fewer than seven PAA AVG coins [...] and of those only two were die duplicates, so the seven coins were from six different obv. and six diff. rev. dies."

Two more examples, with different obverse and reverse dies, are here: Antoninianus of Gallienus with reverse legend error PAA AVGG and here: Antoninianus of Gallienus with reverse legend error PAA AVGG. Notice that the incorrect A is differently positioned on these coins.
