Nice piece, I would say that the date is about right. Wilcox was a silverplate company in the late 1800's or victorian era. One thing I wanted to point out is the words Quadruple plate does not mean pre 1900's many other companies marked and used the words Quad plate even used today. As for Wilcox being a high collector trademark, is not necessary the case either. That is a much rarer and harder to find trademark, not like the flood of international, or Onieda name, but not a sought after like the Reed and Barton name. As for the number 100 meaning older, could be the case, but I have seen some this low, but These pattern numbers in many cases was used for many years, and would be hard to date based on the pattern number. The only other thing to make a point on is Silverplate items tend to move really good as far as sells, but usually for low $$.00 at the most, so much silverplate items out there that the market is over saturated in general.
