symbol with a meaning? I did find this site, but not your mark. Maybe send them a picture? It looks old like something from the 1930s, 1940s ? There have been many Hopi, Zuni and Navaho silversmith and some I would say may never be identified. For all I know that mark says it was made in the 4 corners area of Colorado, Utah, Arizona & New Mexico?I think it was just a allusion,from the picture.I looked at it again with glass and couln't see nothing.I see what you saw thowThis reference site may help: Indian Native American hallmarks AL
Also, I just found it helps to enlarge the marked portion, as there's a bi more to it than is readily evident. I can see part of circle with some letters in it above and left of the x.
