Longship
Longships for the most part used two different kinds of anchors. The most common was a natural wood yoke formed from a tree branch. The weight was supplied by a stone passing laterally through the U of the yoke. The top of the yoke was closed by either a length of hardwood or a curved iron head, which kept the stone in place. One side of the head stuck out so it could dig into mud or sand. In the Ladby ship burial in Denmark, a unique iron anchor has been found, resembling the modern fisherman's anchor but without the crossbar. The cross bar may have rusted away. This anchor—made of Norwegian iron—has a long iron chain to which the hemp warp was attached. This construction has several advantages when anchored in deep waters or in rough seas.
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.
