Anchor
An anchor is a device, normally made of metal, used to connect a vessel to the bed of a body of water to prevent the craft from drifting due to wind or current. The word derives from Latin "ancora", which itself comes from the Greek ἄγκυρα ("ankura").
Anchor coinage
The anchor coinage was a series of four denominations of silver coins issued for use in some British colonies in 1820 and 1822. The name comes from the crowned anchor that appears on the obverse of the coins. The denominations were sixteenth, eighth, quarter and half dollars, indicated by the Roman numerals XVI, VIII, IV and II on each side of the anchor. The reverse design was the royal coat of arms.
