Constantine I, called Constantine the Great, was the first Roman ruler to be converted to Christianity. He was the founder of Constantinople (present-day Istanbul), which remained the capital of the Eastern Roman (Byzantine) Empire until 1453. Constantine the Great unified a tottering empire, reorganized the Roman state, and set the stage for the final victory of Christianity at the end of the 4th century. Many modern scholars accept the sincerity of his religious conviction. His conversion was a gradual process; at first he probably associated Christ with the victorious sun god. By the time of the Council of Nicaea (325), however, he was completely Christian, but still tolerated paganism among his subjects. Although criticized by his enemies as a proponent of a crude and false religion, Constantine the Great strengthened the Roman Empire and ensured its survival in the East. As the first emperor to rule in the name of Christ, he was a major figure in the foundation of medieval Christian Europe.

These coins show Constantine at apparently different stages of life—the one quite youthful, the other in middle age. Both reveal him as the strong and proud ruler he was. The man who wears these cufflinks can do so proudly, knowing the coins were part of a great empire ruled by a great man during an exciting period in history.
