1 = Low   -  10 = High

The 1666 Crown has a dual value profile: it is collectable as a second-bust silver Crown and also benefits from Great Fire-year demand. Recent evidence shows Fine dealer stock around the £500 area, certified VF examples around the high hundreds to low four figures, and stronger XF material moving higher. CIS uses that range as market context, then tests the live asking price through fair value, confidence and Buy/Hold/Pass logic.

The 1666 Crown belongs to the second-bust Charles II Crown type and carries regnal edge date XVIII. The year gives it added historic visibility because it coincides with the Great Fire of London, while reference data confirms the same sterling silver Crown standard of 0.925 silver, 30.1g and about 38.6mm.

Description

The 1666 Crown Standard is a Charles II second-bust Crown with strong historic appeal because it falls in the Great Fire of London year. CIS treats it as a standard circulation silver Crown with extra collector attention, where grade and asking price decide whether the coin is attractive or overpriced.
