n1   London, Trier, and Lyons switched to using GENIO POP AVG before Constantine became Augustus.
n2   Ticinum, Aquileia, Rome, and Siscia discontinued GENIO POPVLI ROMANI in favor of SACRA MONETA c. 300. Ticinum resumed it, but with smaller diameter and lower weight, under Constantine c. 312-313, for Constantine and Maximinus II (Licinius seems to belong in this issue, but is not noted in RIC). Rome resumed it, but with smaller diameter and lower weight, under Constantine c. 312-313, for Constantine, Maximinus II, and Licinus. These resumed issues are in RIC VII, not in RIC VI like all the others.
n3   c. 305-6 Siscia minted GENIO POPVLI ROMANI quarter-folles, but not folles.  See my page on the quarter-follis denomination
n4   Serdica was open from c. 303 to 308, just when Thessalonica was closed. It is thought that the key workers from Thessaloncia were moved to Serdica for that interval. There is some similarity of style. 
n5   Cyzicus issued GPR only for Augusti and the same design had legend GENIO AVGG ET CAESARVM NN for the Caesars.  RIC has it at Cyzicus for Maximinus II as Caesar as Cyzicus 37 (page 585), but it says "Confirmation required" so I am not listing it here. If you have evidence it exists, let me know. 
n6  At Alexandria Licinius and Constantine as Augustus reappear with GPR after 312 in RIC VII (not RIC VI).
n7  Constantine as Caesar at Antioch is not rare. It is known from ten officinia, but was omitted from RIC. See under "before 81" at "Not in RIC".

Ostia and Carthage minted in this period, but did not mint the GENIO POPVLI ROMANI type.
