To get an idea of the prices of complete sets of sterling flatware patterns, here are some examples. All these prices include a chest. As a disclaimer, these are just random prices I have come across in various places. I am in no way, a silver appraiser, but the prices will give you an idea of the retail value of some of patterns. And, the range varies from $1,000 to almost $50,000.
