Note:

(1) Follis. Il follis del periodo pesava, secondo il Ric, 8,5÷10g e aveva un asse di conio ad ore 12 o ad ore 6. Raccolgo in tabella le caratteristiche fisiche delle monete della tipologia di figura tratte dai link sopra citati:

Riferimenti	Peso(g)	Asse di conio (ore)	Diametro(mm)
link1	12,13	-	29
link2	9,60	-	28
link3	9,7	-	27,7
link4	8,66	-	29
link5	9,00	-	27
link6	10,57	12	28
link7	9,64	12	27,5
link8	10,40	-	-
link9	8,67	-	28
link10	9,02	6	27

Dall'esame della tabella emerge che il follis in esame ha caratteristiche fisiche (10g, 25mm) comparabili con quelle delle monete autentiche del periodo.
(2) IMP CONSTANTIVS P F AVG (IMPerator CONSTANTIVS Pius Felix AVGustus). Il 1 maggio del 305, Diocleziano, giunto al ventesimo anno di potere, si ritirò dalla vita pubblica, come precedentemente aveva stabilito e altrettanto pretese da Massimiano Erculio, suo co-Augusto. Con l'uscita di scena, i due Augusti assunsero il titolo puramente onorifico di "Seniores Augusti, felicissimi et beatissimi". Galerio Massimiano Cesare e Costanzo Cesare furono promossi al rango di Augusti, rispettivamente d'Oriente e d'Occidente. Ma a guadagnarci fu sopra tutto Galerio. Infatti, anche se Costanzo, come Augusto senior, possedeva il supremo potere legislativo, come era stato quello di Diocleziano prima di lui, fu Galerio a scegliere, tra uomini certamente a lui fedeli, i due nuovi Cesari nelle persone di Flavio Valerio Severo (Cesare d'Occidente) e Valerio Massimino Daia, suo nipote (Cesare d'Oriente).
(3) SALVIS AVGG ET CAESS FEL KART (SALVIS AVGustis ET CAESaribus FELix KARTago - Beata Cartagine, essendo gli Augusti e i Cesari in buona salute). Monete con la stessa tipologia del rovescio furono battute nel nome di ciascuno dei tetrarchi:

• IMP CONSTANTIVS P F AVG, Costanzo I Cloro Augusto, Ric 39a, la moneta di figura;
  
• IMP MAXIMIANVS P F AVG, Galerio Massimiano Augusto, Ric 39b,
• FL VAL SEVERVS NOB CAES, Severo Cesare, Ric 40a,
• GAL VAL MAXIMINVS NOB CAES, Massimino Daia Cesare, Ric 40b.

(4) è il segno di zecca. In esergo la lettera A, corrispondente al numero greco 1, indica l'officina monetale che ha battuto la moneta
