If anyone wants the lettering >
"SEMINARIO CONG. EN EL MILENARIO DEL MARTIRIO DE SU TITULAR", [0.925 - 1925]
which translates to "Seminary Congregation on the Millennium of the Martyrdom of its Titular".
First side “S. PELAGIO MARTIR”.
Saint Pelagius was a young boy who was martyred in Córdoba, Spain, in 925 AD.
He is a revered figure in the Catholic Church, particularly in Spain and Portugal.
So 1925 is the millennium anniversary.
