The coin is offered by a vendor in China and is described as "Rare PETER II - 1 Rouble 1690 Silver coin--EF".
Why a rouble of Peter II (1727-29) was struck in 1690, well before he became Tsar, let alone before he was born, is unexplained.
The supplied picture (showing a coin dated 1690) bears a certain resemblance to a silver coin (an ecu, perhaps) of Louis XIV of France.
