I'd like to know too, I have a silver ring with no other mark, just 306
About 306 pounds in todays money
100-450 usd
306 kg = 674.614 lb
50-500 usd
It is: 0.05*306 = 15.3 discount
A mark of "306" on silver jewelry typically indicates that the piece is made from 92.5% sterling silver, which is a common standard for silver jewelry. This means that the jewelry is composed of 925 parts pure silver and 75 parts alloy metals.

About 15 to 20 pounds from a scrap yard, definitely worth thinking about, save a lot of money.
