Massachusetts had no coin of its own until 1652. Trade ran on barter and on whatever foreign silver came in, much of it light or counterfeit Spanish money from the West Indies. In May 1652 the General Court set up a mint in Boston and on May 27 named the silversmith John Hull its master, with Robert Sanderson as his partner. No one asked England for leave: Charles I had been executed in 1649, and there was no king to grant one. Anyone could bring Spanish coin, plate or bullion to be melted and returned as Boston money, less the mint's fee.
The law fixed the shilling at three pennyweight, 72 grains, of silver of sterling fineness, about 22 percent lighter than the English shilling. The difference was deliberate: the lighter coins were meant to stay in the colony rather than be exported. Sixpences and threepences were struck to the same standard, and a twopence was added in 1662.
The first coins, struck from June 1652, were simply punched with NE on one side and XII, VI or III on the other. On October 19, 1652 the court ordered a new design with a tree in a ring of beads, MASATHVSETS IN on one side and NEW ENGLAND with the date on the other, so that clipping would show. The tree changed over the years: a willow-like tree until about 1660, an oak until about 1667 and a pine until the mint closed. After the Restoration the mint drew complaints. The king's commissioners demanded its abolition in 1665, and the court answered with a gift of masts for the navy. Hull's contracts were renewed in 1667 and 1675, and the mint finally stopped in 1682. Two years later the colony's charter was annulled, and the mint was among the charges against it.
