Princess pattern Crown silverware, vintage silverplate flatware luncheon set for 4

Vintage Crown Princess pattern silverplated flatware set, a luncheon service for four. There's four each of the grill forks, salad forks, soup spoons, teaspoons and knives.

This silver plate is very tarnished, though we found it in the original cardboard boxes. The boxes were very worn, but I don't believe the flatware has ever been used.
