commemoration of the one hundredth anniversary of the admission of the State of Illinois into the Union."
When approved, this Act became noted as Public Law 65-163.

diameter, device and design, as shall be fixed by the Director of the Mint, with the approval of the Secretary of
the Treasury, and said fifty-cent pieces shall be legal tender in any payment to the amount of their face
The law concluded the authorization with the Proviso: "That the Government shall not be subject to the expense
