At the Wikipedia article about Coins of the US Dollar (https://en.wikipedia.org/wiki/Coins...tates_dollar) it is mentioned that AMF built a silver-removal machine in the 60's to separate silver from clad. (Quoted below). There is no attribution listed.

Is there truth and/or documentation to this?

Article snippet listed below:


Quote:
AMF York was given the contract to design and build a machine to remove silver coins from circulation. Amf engineering built 6 machines for the US mint that operated on the basis of sound made when coins were bounced off an anvil at high speed. A shuttle divered clad coins from silver coins at a speed faster than the eye could follow. The majority of silver coins were removed from circulation in one year.

Don't remember hearing about those machines.
Certainly is believable.
I was still finding a lot of silver coins in circulation during that time period.
I would guess the machines were used to sort the large bags from treasury vaults.

The Royal Mint had a machine to sort 925 from 500 from cupronickel, although I understand it wasn't actually used on a large scale.

I do know the Fed had at least two such machines and they processed all the dimes quarters and halves that were shipped back to the Fed from around 1968 to 70. The US Mint would not have had any use for such a machine. They made the coins and they kept silver and clad production separate. So they would have no reason to run their coins through such a machine. And the Mint did not receive coins, they just shipped coins out, so there would be no old coins there needing separation.
