four old (?) name pins

Hi,
I have had these old name tags for a long time. They range from 2¼" long to 2" and 1¾ long. The pins in the back back me think older but ??????? The white porcelain has two brass pins like the cells on cloisonne. Anyone ID them for me please.

How wide? Maybe military ribbon bars. Framed ribbons were unit awards.

 

They look like old name badges, especially the middle one. The design was pretty common; some of them seem to have a loop for a ribbon.

 

Like this.

 

Hi,
Sorry i thought I put the width on them. They are ¾" wide. I always thought they were name tags also. The porcelain one is only ¼" wide. I think they are too small for ribbon medals. The two bigger ones has a "Greek Key" design, the small one has the wrapped Roman design. (like the roman torches on the old dimes.)
