On October 19, 1652, the Massachusetts General Court decreed that "for the prevention of clipping of all such pieces of money as shall be coined with-in this jurisdiction, it is ordered by this Courte and the authorite thereof, that henceforth all pieces of money coined shall have a double ring on either side, with this inscription, Massachusetts, and a tree in the center on one side, and New England and the yeare of our Lord on the other side. "These coins were the famous "tree" pieces. There were Willow Tree Shillings, Oak Tree Shillings, and Pine Tree Shillings" minted by John Hull and Robert Sanderson in the "Hull Mint" on Summer Street in Boston, Massachusetts. "The Pine Tree was the last to be coined, and today there are specimens in existence, which is probably why all of these early coins are referred to as Pine Tree shillings."    The "Hull Mint" was forced to close in 1683.   In 1684 the charter of Massachusetts was revoked by the king Charles II.
