“The front of the medal shows St. Benedict holding a cross in  one hand and the book of his Rule in the other.

Flanking him  on each side are the words: 
Crux S. Patris Benedicti (The Cross of the Holy Father Benedict).  Below his feet are these words: 

Ex S M Casino MDCCC LXXX  (From the Holy Mount of Cassino, 1880).

On that date , Monte Cassino was given the exclusive right to produce this medal.  Inscribed in the circle surrounding Benedict are the words:

Ejus in obitu nostro presentia muniamur (May  his presence protect us in the hour of death).

The other side of the medal is where the real exorcist force reveals itself.

In the center is the Cross. Benedict loved the Cross and used it to drive away demons. The vertical beam of the Cross has five letters:

C.S.S.M.L.,  meaning Crux Sacra Sit Mihi Lux (May the holy Cross be for me a light).”
