Knox completed a draft bill, intended to repeal many antiquated legal provisions, and to rewrite others. He proposed to eliminate the standard silver dollar (he proposed a lightweight silver dollar that would have a low legal tender limit), move the office of the Director of the Mint from Philadelphia to Washington, eliminate the Mint's charge to strike gold bullion (then .5 percent), and abolish the office of Treasurer at the mints and assay offices, transferring its functions to the superintendent. In drafting the bill, Knox consulted with a number of former Mint officers besides Linderman, such as former directors James Ross Snowden and Robert M. Patterson, as well as former Philadelphia Mint Chief Coiner Franklin Peale. Mint Director James Pollard submitted the bill to Congress on April 25, 1870.
