Hello!
Today I share with you my last new entry:




D\ IMP CLAVDIVS AVG
R\ SPES AVG,  mint mark II on the right field
RIC online n. 633 (ex RIC 191), Siscia mint.
Bust type A3: Head right, radiate, with traces of drapery to front and rear of truncation

Ref.: http://www.ric.mom.fr/en/coin/633?tempRIC=&asmSelect0=&Reign=Claudius+II&asmSelect1=&asmSelect2=&asmSelect3=&asmSelect4=&asmSelect5=&asmSelect6=&asmSelect7=&asmSelect8=&asmSelect9=&asmSelect10=&BustCodeAssoc=A3&asmSelect11=&BustDescription=&ReverseDescription=&Note=&Reference=&page=1&mod=result&hpp=100&from=advanced

This antonininianus is not so common for its type bust. The total amount of ant. of Claudius II listed on RIC is 1041 and only 39 have this bust type.
In particular, for this specific type, the RIC online lists only 5 specimens.
