1933 Sunday School Reward Pin (leaf-shaped)

I recently found a 1933 Sunday School Reward pin and am trying to locate more information and, perhaps, a value.

I have been unable to find this design on the internet under religous medals or sunday school reward pin.

My pin is a bronze color, but it could also be dirty. I have not tried to clean it. The shape is a leaf with five points. The stem is at the top of the pin. The lettering is "S.S. Reward 1933."

I don't know enough about jewelry to accurately describe the back, but here goes...
The pin is a single piece of metal which bends into a circle at the top. The circle appears to be pinched between four small pieces of metal. It has a limited movement.

The pin secures in a curved piece of metal at the bottom.

Thanks for any information you can provide!
