Banks Hamilton helped found the United States Mint; the first national bank; a "System of Cutters", forming the Revenue Cutter Service, (later combined with other government entities to form the United States Coast Guard) and an elaborate system of duties, tariffs, and excises. In five years, the complete Hamiltonian program replaced the chaotic financial system of the confederation era with a modern apparatus that gave the new government financial stability, and gave investors sufficient confidence to invest in government bonds.
