What does 257 stamped on silver mean?

Answer 1

Well honey, 257 stamped on silver means it's 92.5% pure silver, which is the standard for sterling silver. The other 7.5% is usually copper or another metal to give it strength. So basically, it's just a fancy way of saying "this ain't no cheap knockoff."
