> [@ratatoskK](#): > > And yes, people did hoard the silver ones for a while. At least till I was 10 or so, when suddenly there was a wave of advertising in the papers and on TV for Silver coins (mid '70s I think - perhaps later, with the Hunt brothers silver rush? It was very pervasive) - my parents cashed in their (rather small horde) of silver coins at that time, and many of the neighbors did the same. Man, we were quite the herd generation back in the '70s - I remember one time there was a rerun of a Dennis the Menance episode where he was collecting coins, and the week after that a few dozens of us boys at school suddenly became numismatists (luckily there was no general-access Web back then, or we all would have been experts too 😛 )… ---

It was very pervasive) … I can tell you exactly when it hit, in early 1979. About two weeks AFTER I cashed out my old coin collection.:smack: ---

> [@ralph124c](#): > > Actually the big reason for the withdrawal of silver coins: lyndon Johnson needed money to finance his idiotic vietnam war. The treasury realized a profit on the silver, and johnson got a few billion$ extra to blow on his pet project. **Moderator advice.** **Ralph**. If you can back up your assertion with any factual information, then do so. If you can’t then don’t bring idiology into General Questions. [/end Moderator advice] [begin posting as poster] The bad old gummit didn’t “withdraw” silver coins from circulation. All they did was to change the composition in 1965. They withdrew **nothing** from circulation. The public withdrew silver coins and made whatever profit there was by selling them for their scrap value. The Treasury realized NO profit on the silver. Johnson got bubkes. Wait! He got _tsuris_. 🙂 ---

> [@Q.E.D](#): > > All of them do, albeit indirectly. They use magnetic induction much like a typical beachcomber’s metal detector which applies a time-varying electromagnetic field at a particular frequency to the coin under test and measures the resulting induced electric field. The strength of this field is directly related to the electrical conductivity of the coin. IIRC this was an issue that needed to be addressed when they started making the Sacagawea dollar coins. They needed to have similar properties to the older dollar coins so that the few machines that accepted them would take both old and new. ---
