Rogers Lunt & Bowlen

I just recently purchased two butter knives at a estate sale. One of the blades says “stainless” and the other has no mark on it at all, but it looks like some sort of silver plate. The handles on both knives say “sterling handle” with the makers mark imprinted between the words sterling and handle. I believe the makers mark belongs to Rogers, Lunt and Bowlen. The handles do not appear to be solid. I was wondering how much these knives might be worth. Any help is greatly appreciated.

I finally got around to taking some pictures. Hope this helps.
