one of the hallmark reminds me the double-headed imperial eagle with spread wings. I note that it is worn. Through the history of the hallmark changed here is an example of Russian hallmark of St. Petersburg 1700-1730
Thanks AG2012, I'm not finding never similar stamps (a long collects antiques) may have been false hallmark, that possibility is mentioned and Oel. The problem is as hallmark is worn. Mostly I look like 1886. In the egg are repeated two other trademark but not the "years" all are poorly visible.
Oel and Goldstein thank you for your answers and opinion. I think the year 1886, hallmark is worn out. In my opinion, the style could fits with this year. 19th Century Russian Filigree Egg Silver 84 with Lion inside Year 1873 looks like this https://www.925-1000.com/pics/Ximg.jpg https://www.925 ...

Can you help me with identification? I never before found the hallmark year without initials. Details outside the precise and beautiful while the three lions in roughly done. What do you think about this silver egg?
