I recently got this rare bust type for Constantine with a "Prince of Youth" reverse. This honorific usually referred to the young heir apparent; but Constantine was around 40 years old when this coin was issued. He apparently ejoyed the title, perhaps trying to seem younger, and a variation was used as late as A.D. 320 with the VICTORIAE LAETAE PRINC PERP reverses; which translates as "Joyous (well-earned) victory to the eternal Prince" Here is my latest from London Constantine I A.D. 311- 312 23mm 4.2g CONSTANTINVS P AVG; Laureate, helmeted, and cuirassed bust left, holding spear forward and shield.
