U.S.N. Spoons & U.S.C.G. Dinner Plate

Looking for info on these items. The spoons (only one tsp and several tbsp) have U.S.N. (U.S. Navy) engraved on the front and Reed & Barton stamped on the back.
The dinner plates (only have 2) have United States Coast Guard 1790 design/logo on the front and the back is stamped with Nathan Straus & Sons New York.
The spoons look old and my Grandfather was in the Air Force during WWII so I was wondering if this was something he may have came home with.
The dinner plates don't look as old.

just for reference.......while you are finding your way around here..

Neither are Antiques, & the spoons go better in Metal ware...while the plates are better served in the Pottery Forum.

That said....leave well enough alone...& see if answers are forth coming....!

 

Military items are collectible.

Here is a saucer that sold for $8.99 on eBay.

Manufactured by a different maker than yours, but I doubt that the maker matters.
