I need help identifying a small hammered silver coin, weighing 0.41 g, which seems to belong to the Romanov period, possibly issued under Tsar Alexis Mikhailovich (1645–1676).
The overall style matches Russian wire kopeks, but the Cyrillic inscription does not conform to standard types listed in reference catalogs such as Krause, Bitkin, or Rylov & Sablin.
