Chert Madison type arrow point, mid-17th century, eastern New York, Cook Collection , UConn

The bow and arrow represents one of the great technological advancements in weaponry in the ancient world. In fact, the bow is the first mechanical device that could store energy, as the arrow was held in the string before its release. Recent distance records in flight archery for pulled bows are around one third mile, the longest crossbow shot is 1.16 miles! Bows and arrows were used just about everywhere in the world except Australia where spear throwers were the preferred weapon. Triangular shaped arrow points were one of the most common types of arrow points used on the tips of arrows.

Silver 1662 Oak Tree twopence, Hull Mint, Boston, from Windsor, CT

The Willow Tree series was replaced because of a new technology. Rather than simply using the older hammer striking method Richard Doty has suggested Hull changed to a rocker arm press. The dies needed for a rocker arm press were quite different from dies used in the hammer strike method. A rocker press used large-sized rectangular shaped dies with a curved face so that the die could rock back and forth. The image for the coin was then engraved on the curved face of the rocker, one rocker for the obverse and another for the reverse (click here for picture of rocker dies). The two rocker dies would then be mounted face to face in the press. By pulling a lever the upper and lower rockers would press against each other with a rolling motion (click here for picture of a rocker press). As long as the two dies were properly aligned a blank planchet placed between them would be impressed with the design of the dies.
