Bargained for Rosary.

Went to Dublin's Flea Market today. although it doesn't come close to

Santa Cruz's antique fair/ flea markets, or Los Angeles Rosebowl,

I did find this gem, vintage rosary beads. 

Although I am not of the practicing faith, I love 

love religious "brickabrack".

Anyway there are five silver tablets-on each tablet the front says:

 Roses of Joy

Thorns of Sorrow

Palms of Glory

Then the backs say:

1st. 

J) Annunciation

S) Agony in Garden

G) Resurrection

2D

J) Visitation

S) Scouring (difficult to read)

G) Ascension

3D

J) Nativity 

S) Crowning with Thorns

G) Descent of Holy Ghost

4th

J) Presentation

S) Cross Carrying

G) Assumption

5th

J) Finding of Jesus

S) Crucifixion

G) Crowning of Mary

Pat. Pend.

The Cross

Jesus

Mary

Joseph

Be With Us

On Our Way

Does anyone know what the J, S, G stand for? And is this universally found on all rosary beads?
