Though he was frustrated in the tariff battle, Morris continued to implement and propose other economic reforms. In January 1782, after receiving its charter from Congress, the Bank of North America commenced operations, and the bank's currency soon achieved wide circulation. Morris sought the establishment of a national mint to provide for a single coinage throughout the United States, and proposed the first decimal currency, but Congress was unwilling to back this project. He appointed several receivers, including Alexander Hamilton, to help circulate banknotes, report on the prices of goods, and perform other functions in places throughout the United States. He also reformed government procurement of supplies, saving money by placing the onus for the storage and transport of supplies on government contractors.
