I have a hallmark on my iris flower pin which appears to read CNR. The word STERLING is on top of hallmark, and G.S. Pin on bottom of hallmark.

any help would be appreciated!

thanks,

Mike

Hello Mike.
What appears to be a CNR mark might be the CMR mark used by the Charles M. Robbins Company, Attleboro, Massachusetts.

They produced medals, badges, medallions, along with many other items.
They also made commemorative, advertising, insignia, souvenir, religious and organizational jewelry.
Don't know what the GS stands for.

Pat.

Thank you for your help Patrick!
