I just got two more Failmezger plate coins,
Constantius II
A.D. 337-340
17mm 1.5g
D N FL CONST-ANTIVS AVG; rosette diademed, draped, cuirassed bust right
SECVRITAS REI P; Securitas standing facing, legs crossed, head turned right, holding sceptre in right hand, left elbow leaning on column.
In ex. R❦P
RIC VIII Rome 15
Ex Rath March 1989
ex-Failmezger plate #386CS
Though this coin was listed as official, I am sure that it is unofficial; given the lower weight and smaller flan coupled with the reverse spelling error (I'm not sure that the obverse is right either) and some slight style differences.
Magnentius
Circa A.D. 350- 353
19mm 3.2g
DN MAGNENTIVS P F AVG; bare-headed, draped and cuirassed, A behind bust.
GLORIA ROMANORV; Magnentius on horseback spearing barbarian.
In ex. RPLG
Cf. RIC VIII Lyons 115
