Divus Nigrinian, son of Carinus. AV Aureus ca 284 AD, 21 mm, 4.66 g. 

Obv: DIVO NIGRINIANO Bare-headed bust r. 
Rev. CONSE–CRATIO Nigrinian in facing biga on funeral pyre.

Calicó 4412 = Ponton d’Amécourt 594 (this obverse die). 
Cohen 1; RIC V-II 471.

Of the highest rarity, possibly only the third specimen
 known, one of the two still in existence (the third,
 pierced, was stolen in the famous robbery at the
 Bibliotèque Nationale de France and was most probably
 melted down). 

An inscription identifies Nigrinian as a grandson of
Carus, but it can only be deduced that he was the son of 
Carinus. It is generally assumed that Magnia Urbica was 
Nigrinian’s mother, but there is no evidence for this. 
If we believe the sketchy and unreliable sources for this 
period, Carinus was one of the great philanderers of his
age and Nigrinian could have been born of any number of
women.
