Some ancient sources (Eusebius. The History of the Church 6:34) say that Philip, Roman emperor from A.D. 244-249, was the first Christian emperor. This passage is from the Origo Constantini -- "This Constantine was the first Christian Emperor except for Philip (the Arab) who, or so it seems to me, became Christian simply in order that the thousandth year of Rome might be said to belong to Christ rather than to idols." .This was probably just a rumor started in an attempt to make Philip look bad before the Roman state accepted Christianity. The first coin with Christian over-tones may have been issued in the name of Salonina (260-268 A.D.), wife of Gallienus. There has been speculation that she was a Christian because a coin issued in her name had a reverse with the inscription AVE IN PACE (RIC V part 1 Mediolanum 58). There is no doubt that Constantine was the first emperor that embraced Christianity, though, and this page investigates the numismatic evidence of Constantine's conversion.
People who expect to find Christian imagery on bronze coins of Constantine will be disappointed. “Of approximately 1,363 coins of Constantine I in RIC VII, covering the period of 313-337, roughly one percent might be classified as having Christian symbols.”1 The first instance of a chi-rho on a coin of Constantine is on a rare silver medallion issued from Ticinum in 315. This page is about the bronze coinage, though. There is only one bronze reverse that has a symbol associated with Christianity as part of the design- RIC VII Constantinople 19 & 26. There are more coins with symbols used as field marks, though. There is a VLPP from Siscia that has a chi-rho in the crossbar of the helmet, but it only occurs a few times, and then only in officina B. There are also the "eyes to the heavens coins", but this is not a solely Christian image; Greek coins used this upward gaze long before Constantine did.
The field marks that have Christian significance consist of chi-rho’s and crosses. “Early Christian crosses came in several forms including the equilateral or Greek +, the letter tau T, the letter chi X sometimes called St. Andrew’s cross, the tau-rho monogram and the Latin cross crux immissa.”2 There is a question whether these symbols actually had any Christian relation. The chi-rho appeared for the first time in the third century B.C. on a Greek bronze of Ptolemy. Field marks served an internal function, and the mint supervisor probably picked the control mark. Since Constantine had been portrayed with Christian symbols on the silver medallion issued in 315, "mint supervisors thereafter felt free to use Christian signs as control marks or decorative embellishments on imperial coinage...In doing so, they were reflecting the emperor's veneration of Christian signs and his practice of employing them on his war helmet and military standards."3
It is not so important what imagery Constantine used; but rather, it is more important what imagery he did not use. By 324, Constantine was the sole ruler of the Roman Empire and: "he did all this without attributing his success in any way to correct religio toward the ancient gods. It was in this pointed absence of piety toward the gods, as the traditional guardians of the empire, that his subjects came to realize that their emperor was a Christian."4
Constantine also had to remember not to alienate the military. Constantine owed his position to the army, and he surely realized this. Constantine may have been a Christian, but the army at this time was mostly pagan. The word pagan comes from paganus, which means rustic or pertaining to the country, and most soldiers of the fourth century came from the provinces, or the country. Christianity took longer to spread to the countryside, so that is why the word pagan came to be associated with non-Christians.
On
some commemorative coins, Constantinopolis
is holding a cross- scepter with a globe, often topped with a smaller globe,
which may have had some religious significance. For more on this cross-scepter

page.

So the SPES PVBLIC reverse "is the first coin type where the design explicitly proclaims Constantine's new faith."5 Some people may wonder why Constantine took so long before using Christian symbolism in an overt fashion on his coins. Constantine had to exercise some caution and not upset too many people, especially the army. "He was careful, and that was why his Christianization of the empire was only gradual...reflected in the slow and for a long time minimal infiltration of the coinage by Christianity."6
Constantine, and Eusebius, compared serpents/dragons to evil on many occasions. In one instance, when he referred to Arius, Constantine talked about the serpent and the Devil as if they were one.
"Take heed,
everyone take heed, how sad he sounds, when pierced by the serpent's sting
[that is the Devil's]."7
Constantine also used the dragon/serpent symbolism to specifically describe Licinius.
"Like some wild beast, or a twisting snake coiling up on itself."8
"But now,
with liberty restored and that dragon driven out of the public administration
through the providence of the supreme God and by our service."9
"The references to "liberty...restored" and the perishing dragon-serpents
in the palace sermon and the episcopal letter must be the literary twins
of the LIBERTAS
PVBLICA and the pierced dragon coins issued about the same time." 10
Eusebius
also described a painting that Constantine placed above the door to his
palace.
This he displayed on a very high panel set before the entrance to the palace for the eyes of all to see, showing in the picture the Saviour's sign placed above his own head, and the hostile and inimical beast, which had laid siege to the Church of God through the tyranny of the godless, he made in the form of a dragon borne down to the deep. For the oracles proclaimed him a 'dragon' and a 'crooked serpent' in the books of the prophets of God (Isaiah 27:1); therefore the emperor also showed to all, through the medium of the encaustic painting, the dragon under his own feet and those of his sons, pierced through the body with a javelin, and thrust down into the depths of the sea.11
The coin shows three medallions on the standard. The medallions were portraits
of Constantine I and two of his sons. The sons were probably Constantine
II and Constantius II, as Eusebius said that Constantine personally showed
him the standard. Eusebius did not meet Constantine until 325, and Crispus
was dead by 326, so the other two sons are the most likely candidates to
have been represented on the standard.
The symbol of the Saviour's name, two letters indicating the name of Christ by means of its initial characters, the letter P being intersected by X in its centre: and these letters the emperor was in the habit of wearing on his helmet at a later period. From the cross-bar of the spear was suspended a cloth, a royal piece, covered with a profuse embroidery of most brilliant precious stones; and which, being also richly interlaced with gold, presented an indescribable degree of beauty to the beholder. This banner was of a square form, and the upright staff, whose lower section was of great length, bore a golden half-length portrait of the pious emperor and his children on its upper part, beneath the trophy of the cross, and immediately above the embroidered banner.12

The ‘eyes to the heavens’ bust type was officially issued in bronze in
three reverse types. It was used for VOT XXX, PROVIDENTIAE AVGG and DAFNE
types. Sometimes this bust type turns up on CONSTANTINOPOLIS and VRBS ROMA,
but this was probably more of the engravers decision than an official design
from the mint. It may even turn up on other coins, like this votive from
Siscia.
it may be a complete accident that it has a slight tilt to the head or
an example of artistic license on the part of the engraver.
It was used more in eastern mints, maybe because Constantine was shifting
his capitol to Constantinople. Why did Constantine use this bust type?
This type was probably copied from an earlier Greek design, but what, if
anything, prompted the use of this type? This type was being issued
circa 325-6. During this time, Constantine summoned the Council of Nicea
in 325 and celebrated his vicennalia (15 year anniversary). Eusebius tells
us this type was issued because of the religious conviction of Constantine.
Constantine was also in the process of moving the capitol to Constantinople
at this time. It seems likely that Constantine was sending a message
to the world with the 'eyes to the heavens' coinage. A message of his increasing
beliefs and convictions.
"How deeply
his soul was impressed by the power of divine faith may be understood from
the circumstance that he directed his likeness to be stamped on the golden
coin of the empire with eyes uplifted as in the posture of prayer to God:
and this money became current throughout the Roman world." Eusebius (IV.15)
