Steam-Powered Coin Press | The Franklin Institute

"On the 23rd of March last (1836), the first steam coinage in America was executed at this Mint; and the performance of the press, in which the power of the lever is substituted for that of the screw, has answered all our expectations. Since that time, all the copper coins have been struck by this press, and it has been lately used with success for coining half dollars. The workmen are now engaged in making other steam presses; and as these are completed, the coining by human labor be abandoned, and the work that can be executed in...the Mint will be greatly increased."
