Pyotr Baskakov, Russian Silver, Kokoshnik Mark

Looking for assistance valuing this set of 6 napkin rings. They are Russian Silver stamped with Peter Baskakov’s mark and the Kokoshnik mark of 83 and the sideways head (1908-1917). This is a complete set with the total weight of 313.5 grams. They are beautiful!

Any information or thoughts on the value or history would be greatly appreciated!

Just realized I put 83…I meant 84! Anyone out there know anything about this lovely set or the maker?
