Need Help identitying Hallmark US 915 Ring

[Shauna13]

My Grandma left me this ring. Everything I have found on Silver Hallmarks for .915, is Spain Silver with a star hallmark. This says US 915. I have found many sites that say it is 22k white gold. It can not be acid tested because of the protecting alloy. There is a place in Medford Or that accepts 915 gold. Any help would be appreciated.

This is the best pic I could get today. Will try for a better one.

Hello Shauna,

That's not a hallmark, but a mark denoting the purity or fineness of the silver. Silver Standards of the World - Encyclopedia of Silver Marks, Hallmarks & Makers' Marks
