By the middle of the third century CE, the Roman Empire was in bad shape.
In 253, when Valerian became emperor, the Empire had had 10 rulers since the death of Severus Alexander in 235. Most of these men had killed the preceding emperor and then taken over; several were generals who had won a battle or two against the barbarians and decided that they themselves would make better emperors.
In addition, there were constant incursions across the borders into Roman territory by barbarians like the Alemanni, Goths, Marcomanni, and the Juthungi, and by the Sassanid Persians. Two large sections of the Empire broke away as independent entities: the Gallo-Roman, centered on Gaul, and the Palmyrene Empire, centered on Syria. The loss of wide swaths of the Empire destroyed much of the tax base, and larger armies required more money, so runaway inflation was also a threat to effective governance.
So Valerian had his hands full when he became emperor, and, along with his son Gallienus, he had to work hard to recover the Empire. Things got worse when Valerian was captured by the Sassanid king Shapur I in 260 and died in captivity. Gallienus had some success in restoring the Empire, but his generals didn’t think he was up to the task and subsequently murdered him in 268. Three of the emperors that followed Gallienus were outstanding generals and are referred to as the Illyrian Emperors: Claudius Gothicus (268-270), Aurelian (270-275), and Probus (276-282). They managed to reconquer the breakaway Gallo-Roman and Palmyrene Empires and drive back the invaders, and by the time of Probus’ death, the Empire had recovered much of its strength.
It was at this point that Carus became emperor.
The History
Very little is known of Marcus Aurelius Numerius Carus’ early life. Most scholars believe he was born in Narbo, Gaul, around 224. He was educated in Rome, and as a Senator he served in various civilian and military capacities before becoming praetorian perfect under Probus in 282. In 283, Probus was killed by mutinous troops at the Pannonian city of Sirmium (which happened to be his birthplace). Carus was proclaimed Roman emperor by the army and sent an announcement to the Senate stating so. He didn’t travel to Rome and paid no heed to the will of the Senate.
Carus had two sons: Marcus Aurelius Carinus and Marcus Aurelius Numerianus. He raised both of them to the rank of Caesar but in early 283, he raised Carinus to the rank of Augustus and put him in charge of the Western part of the Empire. Carus took Numerian with him back to the east to confront the barbarians and the Sassanids. While in the Balkans, Carus campaigned against the Quadi and the Sarmatians on the Danube where he reportedly killed 16,000 Quadi and captured 20,000. For this he was awarded the title Germanicus Maximus.
Before his death, Probus had been planning a campaign against the Sassanid king Bahram II, and Carus decided to go ahead with the war. In 283 CE, Carus invaded Mesopotamia, defeated a Persian army, and captured both Seleucia and Ctesiphon, the Persian capital. Mesopotamia was once again a province of the Roman Empire, and Carus took the title of Persicus Maximus. However, Carus soon died under mysterious circumstances. After a stormy night in either July or August, he was found dead in his tent, possibly killed by lightning. It’s more likely that he had been killed by Arrius Aper, the praetorian prefect and father-in-law of Numerian, or by Diocletian, the commander of the imperial bodyguard.
Now serving as Augustus, Numerian was not as warlike as his father and withdrew from Mesopotamia, returning it to Persian control. The emperor’s entourage moved back across the Tigris and headed toward Rome. He was said to have an eye infection that had him riding in a closed coach. When the coach reached Bithynia or Thrace, a rotting smell was coming from inside, so when it was opened, the dead body of Numerian was found. Diocletian accused Aper of the murder and killed him, whereupon Diocletian was declared emperor.
Carinus headed east to confront Diocletian, and the two armies met at the Margus River in Moesia. Either Carinus won the battle but was killed by one of his tribunes or Diocletian completely defeated Carinus’ army. Whichever version is true, Diocletian was the last man standing and thus became emperor.
Carus
There were several mints in operation at this time: Antioch, Cyzicus, Lugdunum, Rome, Siscia, Ticinum, and Tripolis. The mint at Serdica was closed by Probus. Carus reduced the wight of the gold aureus to 4.6 grams but raised it back to 5.4 before the end of his reign. All the mints issued gold aurei and antoniniani, except Tripolis, which only issued antoniniani. This may explain why there seems to be a lot of gold coins from an emperor whose reign lasted less than a year.
Figure 2a shows an attractive aureus of Carus, and Figure 2b shows an aureus of his sons, Carinus and Numerian, that was minted after Carus’ death.
The antoniniani varied in quality from mint to mint but some could be quite appealing. The two examples in Figure 3 show this variety. Figure 3a shows a well-silvered coin of Carus indicating that the reforms that Aurelian had implemented were still in practice. Figure 3b is interesting because it shows Carus wearing a military helmet. This obverse had been used to a limited extent under Claudius Gothicus and Aurelian but then became more popular under Probus.
The Rome mint produced a number of other denominations. These included the denarius, the quinarius, and the bronze as. Figure 4 shows all three of these denominations. Figure 4a shows an attractive denarius very similar to those produced by the previous emperors, as is the quinarius in Figure 4b. Both these denominations are scare and can be costly to buy in good shape. The bronze coin in Figure 3c has been referred to as a semis and reduced-sestertius, but most numismatists call it an as. There are only three types of these listed in the RIC, and they are very rare.
There is one additional bronze coin that was minted only at the Siscia mint and it is shown in Figure 5. It has the bust of Sol facing the bust of Carus on the obverse, and the reverse has Felicitas facing left. This coin was originally minted by Aurelian, who made Sol his personal god and introduced the cult of Sol Invictus to Rome. The cult became very popular, so Carus utilized this in his reign to associate himself with Aurelian. There has been some question as to this coin’s denomination. Even though the coin is not double the weight of an antoninianus, the double radiant crown on the obverse may have meant that it was worth two antoniniani in the marketplace, hence “double” antoninianus.
There were also a number of coins minted by Carus that include both Carus and his son Carinus on one side or the other. The coins included aurei, antoniniani, gold quinarii, and denarii and tend to be relatively rare.
Numerian
Numerian was given the title of Caesar in late 282 by his father and retained this title until early 283 when he became Augustus. Only aurei and antoniniani were minted while he was Caesar; the former are hard to find, but the latter can be purchased at reasonable prices. Figure 6a shows an antoninianus when Numerian was Caesar, and Figure 6b is one when he was Augustus.
Once Numerian was Augustus, his mints began to produced denarii, quinarii, and asses, in addition to the aurei and antoniniani. I could not find examples of asses, so they must be extremely rare. The other three are shown in Figure 7. Figure 7a is an aureus with Victoria on the reverse; Figure 7b is a denarius with Pax reverse, and Figure 7c is a quinarius with Mercury on the reverse. None of these three coins are common and can be hard to find. Only the antoniniani, both Caesar and Augustus, can be purchased at reasonable prices.
Carinus
The coinage of Carinus is similar to that of his brother in that Carinus was Caesar for less than half a year before becoming Augustus and produced coins with both titles on them. But unlike Numerian, Carinus’ mints issued a denarius, a quinarius, a double antoninianus, and an as, as well as an aureus and antoninianus. The double antoninianus and as are very rare, and I could not find any examples of them – though I’m sure the as is similar to that shown in Figure 4c. Figure 8 shows an aureus for Carinus as Caesar on the left and an aureus as Augustus on the right.
When Carinus became Augustus, mints continued to produce the same denominations, except that the double antoninianus was dropped and the gold quinarius was added. Like the double antoninianus and as, I could not find any examples of the gold quinarius. Figure 9 shows three of the Augustan denominations. Figure 9a is an antoninianus with Victoria on the reverse; Figure 9b is a denarius with a quadriga (a four-horse chariot) on the reverse; and Figure 9c is a quinarius with Virtus standing on the reverse. The denarius and quinarius can be hard to find and expensive, but the antoninianus is readily available on the market and can be purchased in excellent condition at reasonable prices.
In addition to the aforementioned coins, Carinus issued a lot of coins that had both himself and his father and/or his brother on them. He also issued divus (posthumous) coins for his father, brother, and for whom was probably his own infant child, Nigrinian. One of these last coins is shown in Figure 10a: the coin is a divus antoninianus of Nigrinian with the standard eagle and CONSECRATIO legend on the reverse. Carinus also struck coins of his wife. Figure 10b is an aureus of Carinus’ wife Magnia Urbica with Venus on the reverse.
Comments
Aside from the antoniniani, the coins of this Roman Imperial dynasty are very pricey and hard to find. The gold coins, of course, and are going to fetch the highest prices, but some of the other coins, like the bronze quinarius and denarius, can command a heavy price even if the coin is not particularly attractive (I have several of these: expensive and ugly). The as and double antoninianus must have been very limited issues since it’s hard to find photos of them, let alone one for sale.
