Russian Forks

 I was going to make jewelry out of them..but after a little research I decided they were to rich in history to turn into bracelets and rings.  I know they are Russian, and the "84" means silver.  I was given one online appraisal of "at least $350," and here I am for hopefully some more knowledgeable opinions. 

Sorry for the quality of the close-ups.  There is, like I said before, a fleur-de-lis with two letters.  They look like "ED" or "FD" or even "LD"  I'm thinking it might be Russian letters.

Thanks so much,
