It does appear to have a dot before PTR. What does this mean exactly?
It means that you had it right at first as RIC 254 rarity of R4, but like I said originally, the VIRTVS-EXERCIT series as a whole is not rare at all, so the r4 doesn't mean a lot. There are about a dozen variations (different mint mark, obverse legends etc.) of these coins for Constantine from Trier, and all are rated as rare, so all together not rare at all.
