Early Christian Types
The first type to refer to Christianity was struck in 327-328 under Constantine (307-337), but its reference to Christianity, while evident, is obscure. It has provoked many scholarly articles.
This coin: 18 mm. 2.99 grams.
Head of Constantine right, laureate.
CONSTANTI-NVS MAX AVG
Reverse: SPES PVBLIC across the field with A in the lower left field,
a chi-rho topping a standard
with three dots on the vexillum (flag-like object), planted in a serpent with head downward.
CONS (indicating the mint of Constantinople) in exergue.
RIC Constantinople 19
This type was issued only in the first issue of the new mint at the newly founded capitol city of Constantine, Constantinopolis (now Istanbul in Turkey, which was founded on the site of a smaller Greek city named Byzantium, for which the Byzantine empire is named). It must have been unpopular when it was issued in 326 because it was almost immediately discontinued; the other coin types of the same issue are far more common. No other ancient coin type is similar enough to help us interpret this type, and each proposed interpretation has been disputed by some other author with a different interpretation.
"SPES" means "hope" and had appeared on coins many times. A personification of Spes is a common type for the emperor's son and heir apparent. But there never had been anything like a standard planted in a snake. The snake has been interpreted as a symbol of evil in general or, alternatively, as a symbol for Licinius, the defeated rival emperor of the eastern part of the empire. In any case, the interpretation goes, the standard of Christianity defeated them, causing the head of the snake to droop as if in death. The three dots on the standard might, or might not, show medallions portraying Constantine's three sons.
There are many off-site discussions of this type. One is here (a very old Numismatic Chronicle issue on googlebooks). Victor Clark, at http://www.constantinethegreatcoins.com/symbols/ says
Note for collectors: This type is very rare and in great demand. A nice example will cost more than two thousand dollars. At most times there will be none on the market and when the next one appears, which might be year or more off, it is likely to appear in a major auction. The type has been the subject of modern counterfeiting, as described here.
In AD 350 the first type with an overtly Christian legend occurs. Vetranio, ruler in the Balkans during the reign of Constantius II, issued this historically important first type with the legend "HOC SIGNO VICTOR ERIS" ("In this sign, you will be victorious") referring to the famous vision of Constantine prior to the battle of the Milvian bridge on October 28, 312.
This coin: Obverse portrait of Vetranio, who ruled in the Balkans March 15 - Dec. 25, 350.
21 mm diameter. 5.06 grams.
Bust of Vetranio right, laureate, draped, and cuirassed
Legend: DN VETRA-NIO PF AVG, A in field left, star in field right
Reverse: HOC SIG-NO VICTOR ERIS
Victory crowning emperor holding standard with chi-rho, A in field left.

The chi-rho, , (also called a christogram, or, rarely in numismatics, a chrismon) is formed from the first two letters of "Christ" in Greek (chi = X and rho = P).
This is a reference to the famous vision of Constantine before the momentous Battle of the Milvian Bridge against Maxentius just outside Rome on October 28, 312. The ancient author Lactantius who was tutor to Crispus (appointed either 311 or 313) wrote in "On the Deaths of the Persecutors" (c.318-321, Chapter 44, a.k.a. "On the Manner in which the Persecutors died"):
This testimony is reliable (as the next coin supports) and differs from the report written twenty-five years after the event by Eusebius who wrote in "The Life of Constantine":
The standard with a chi-rho is called a "labarum." The coin above has a clear example. Far more Roman coins with early Christian symbols have a labarum with a chi-rho than have a cross.
Note for collectors: Vetranio's coins are scarce so any Vetranio coin is in demand as a portrait piece. This type is also important as an early Christian reference. These two features combine to make the type far more expensive than most fourth-century copper coins. Nevertheless, it is readily available on the market. It is usually fairly well-struck. The chi-rho is small and is sometimes not clear, in which case the historical interest is not illustrated and the coin is less desirable.
The first fully Christian design
Not long after the Vetranio type, the Gallic usurper Magnentius (AD 350-353) issued a large coin in which a chi-rho is the type.
This coin: 27 mm. 8.84 grams.
Bust of Magnentius right, head bare
Legend: DN MAGNEN-TIVS PF AVG
Reverse: SALVS DD NN AVG ET CAES
large chi-rho with alpha and omega on either side.
TRS in exergue (a mint mark for Trier = Treves = Treveri,
in modern Germany, near its border with Luxembourg)
The "S" denotes a product of the mint's second officina [workshop]
RIC Trier 318
The "AVG ET CAES" refers to Magnentius, the AVGustus, and his brother, Decentius,
whom he had elevated to the rank of CAESar.
The type is also issued for Decentius.
Not only is the chi-rho a Christian reference, but so is the alpha (A) and omega (ω) pair. Alpha is the first letter in the Greek alphabet and omega the last. In the book of Revelations (1:8) it says "I am the alpha and the omega, the first and the last." This may refer to God or to Jesus (It is a matter of scholarly dispute which. See Wikipedia for more on that distinction)
Note for collectors: Coins of Magnentius are readily available and this large type is not rare, but because of its manifest Christian connection it is several times as expensive as many other late Roman coin types. It is issued at several mints and also issued for Decentius. The denomination is called a "double maiorina" (or by size, an "AE1") and there is a very similar, but smaller and much less common, (single) maiorina of the same design. Often this type are crowded, with the flans somewhat too small for the dies. Also, this type was widely copied unofficially and imitations are found with workmanship of varying quality, from nearly as good as official mint products to quite crude.
