Looking for a book or booklet about silver.

[Silverfish2910]

Some time ago, I read about a booklet allegedly written by a vending machine maker. He says that in the 60's the Secret Service came to him and wanted to know what kind of counterfeit coins could fool his machines (which at the time accepted silver coins). So he gave the formula for a copper nickel slug which would do the trick.

Later on, when the US Mint pulled silver coins from circulation, lo and behold, the new coins were made with the same formula the vending machine maker gave.

So he wrote this book/ let to tell people about what happened.

Please email me.

Thanks.

This was about 1965, remember? When they got rid of all the silver coins first by debasing them from 90% silver to 40% silver then they finally replacing them with what you Americans use today - 91.67% copper and 8.33% nickel.
