Napkin Rings - any collectors?

[Bugguy]

I started buying these for my wife years ago and the collection has turned out quite nice. There are none later than 1920 and most are in the 1895-1915 range. All are hallmarked English sterling. She prefers them with a monogram as it ties it to a real person. I found this vintage needle display box and its perfect. I still have a few slots to fill.

As I've studied the rings I've learned that collectors look for enameled Russian rings, Chinese and most interesting, British Naval Officer rings that identify every ship the sailed on.

I'd enjoy seeing other collections.
