The subject of a National Mint for the United States was first introduced by Robert Morris,[2] the patriot and financier of the revolution; as head of the Finance Department, Mr. Morris was instructed by Congress to prepare a report on the foreign coins, then in circulation in the United States. On the 15th of January, 1782, he laid before Congress an exposition of the whole subject. Accompanying this report was a plan for American coinage. But it was mainly through his efforts, in connection with Thomas Jefferson and Alexander Hamilton, that a mint was established in the early history of the Union of the States. On the 15th of April, 1790, Congress instructed the Secretary of the Treasury, Alexander Hamilton, to prepare and report a proper plan for the establishment of a National Mint, and Mr. Hamilton presented his report at the next session. An act was framed establishing the mint, which finally passed both Houses and received President Washington’s approval April 2, 1792.[3] NOTES ON THE EARLY HISTORY OF THE MINT. FROM ROBERT MORRIS’S DIARY. 1781. July 16th. Wrote to Mr. Dudley at Boston inviting him hither in consequence of the Continental Agent Mr. Bradford’s Letter respecting him referred to me by Congress. July 17th. Wrote Mr. Bradford respecting Mr. Dudley. Nov. 10th. Ordered some money on application of Mr. Dudley to pay his expences. Nov. 12th. Sent for Mr Dudley to consult him respecting the quantity of Alloy Silver will bear without being discoloured, he says he can put 6 drops into an ounce. Desired him to assay some Spanish Dollars and French Crowns, in order to know the quantity of pure Silver in each. Nov. 16th. Mr. Dudley assayed a number of Crowns and dollars for our information respecting the Mint. 1782. Jan. 2d. Mr. Benjamin Dudley applied for money to pay his Board which I directed to be paid by Mr. Swanwick, this gentleman is detained at the public expence as a person absolutely necessary in the Mint, which I hope soon to see established. My propositions on that subject are to be submitted to Congress so soon as I can get the proper assays made on Silver coins &c. Jan. 7th. Mr. Dudley applies about getting his wife from England. I promised him every assistance in my power.[4] Jan. 18th. I went to Mr. Gouvr. Morris’s Lodging to examine the plan we had agreed on, and which we had drawn up respecting the Establishment of a Mint, we made some alterations and amendments to my satisfaction and from a belief that this is a necessary and salutary measure. I have ordered it copied to be sent into Congress.
