Read an article in the Australian Coin review, many years ago,
about General Motors producing a machine that blanked and struck coins from a rolled bronze sheet, perhaps a metre wide, in a single operation.
Have been unable to find a reference to this minting experiment since. Perhaps someone else in the CCF can.
The minting press was capable of producing hundreds of thousands of One Cent pieces per hour.
The experiment was terminated, because the press required high maintenance hours, the coins themselves came out very slightly oval in shape, and the huge rolled bronze sheet consumption rate.
