I figured every collector of ancient coins should have a Constantine in the collection...so I chose this one.
Billon follis, RIC VII Rome 46 (R5), obverse IMP CONSTANTINVS P F AVG, laureate, draped and cuirassed bust right; reverse SOLI INVICTO COMITI D N, Sol standing left, radiate, nude but for chlamys over shoulders, raising right hand commanding the sun to rise, globe in left, star left, crescent right, R P in exergue (This information comes from the place I bought the coin.)
