According to data I have found this is 20.8 oz of sterling silver. Box and plastic clear cover included. Below is what I found on this set. This is one of the sets with reeded edges, and the medals are not marked as Sterling or. 925, but this set was only issued in sterling silver and gold plated sterling.The walnut display case is nicer than average. This set is not gold plated.
