I purchased a beautiful very heavy Silver Cuff Bracelet on e-bay. It was called a Zuni Bracelet but being from Kingman Arizona I know a Navajo made vs Zuni. The markings inside the Bracelet does have ZUNI stamped with the letters as below spaced rather unusually

ZUNI
E
Y M

I have never seen a Zuni piece like this one but is a common Navajo design. Not sure why ZUNI is stamped other than maybe as a part of the Hallmark. Greatly appreciate anyones ideas on this.

Have a great day, Joe
