1640 (error on label, which states 1665) Swedish Livonia Solidus NGC MS61 Riga Queen Christina
As indicated by the characters on the obverse, the ruler is clearly Christina, Queen of Sweden, who reigned from 1632 to 1654, so the date of the coin cannot be 1665.
It is hard to make out, but I believe the characters on the reverse are:
CHRISTINA · D · G · D · R · S · / SOLIDVS · CIVI · RIGE · 40
It is number 41643 on numista website.
