The true meaning of this reverse type has never been fully deciphered, the latest theory being that the X shaped pattern represents Constantine's vision before the battle of the Milvian bridge. This does not seem likely since the type is known on coins of Licinius, who was not a Christian, and perhaps more importantly, was Constantine's enemy.
