I can't make out the backmark. Can you type it out please. And if you can measure the diameter that would be great

I'll resume my search tomorrow but I believe that particular backmark was used in the late 1860s and 1870s

Looks like #113 in Albert's book.

I am guessing the pendant is Catholic Youth Organization. Very nice piece of silver and a great button!
