The Mint was established by Act of Congress the second of April, 1792, and a few half-dimes were issued towards the close of that year. The general operations of the institution commenced in 1793. The coinage effected from the commencement of the establishment to the end of the year 1800 may be stated in round numbers at $2,534,000; the coinage of the decade ending 1810 amounted to $6,971,000, and within the ten years ending with 1820—$9,328,000. The amount within the ten years ending with 1830 is stated at $18,000,000, and the whole coinage from the commencement of the institution at $37,000,000. On the second of March, 1829, provisions were made by Congress for extending the Mint establishment, the supply of bullion for coinage having increased beyond the capacity of the existing accommodations. The Mint edifice, erected under this provision, stands on a lot purchased for the object at the northwest corner of Chestnut and Juniper streets, fronting 150 feet on Chestnut street and extending 204 feet to Penn Square, (the central and formerly the largest public square in the city). The corner-stone of the new edifice was laid on the fourth of July, 1829; the building is of marble and of the Grecian style of architecture, the roof being covered with copper. It presents on Chestnut street and Penn Square a front of 123 feet, each front being ornamented with a portico of 60 feet, containing six Ionic columns. In the centre of the structure there was formerly a court-yard (now built up) extending 85 by 84 feet, surrounded by a piazza to each story, affording an easy access to all parts of the edifice. Present officers of the Mint: Hon. Daniel M. Fox, Superintendent; William S. Steel, Coiner; Jacob B. Eckfeldt, Assayer; Patterson Du Bois, Assistant Assayer, James C. Booth, Melter and Refiner; N. B. Boyd, Assistant Melter and Refiner; Charles E. Barber, Engraver; George T. Morgan and William H. Key, Assistant Engravers; M. H. Cobb, Cashier; George W. Brown, Doorkeeper. On July 4, 1829, Samuel Moore, then Director, laid the corner stone of the present building, located at the northwest corner of Chestnut and Juniper streets. It is of white marble, and of the Grecian style of architecture, and was finished, and commenced operations, in 1833. Subsequent to that date necessary changes in the interior arrangements, to accommodate the increase in business, have been introduced at various times, and it was made more secure as a depository for the great amount of bullion contained within its vaults, by having been rendered fire-proof in 1856.
