I know back in the 70s some quarters were struck on dime planchets (I have some of them I found back then). It was puzzling the first time I heard one of them b/c as tipping the batch of quarters onto the glass, it sounded like there was a silver one. But there there was no silver. It finally came down to taking a handful at a time, dropping them (not from very high!) until the piece in question was found.
The only thing I remember being confused by is that sometimes a quarter and a nickel (I am guessing slightly off composition) can sound very similar to a silver quarter).

I'd do it but lack the honest experience
Just get one of each denomination in silver and normal metal (don't forget
War Nickels!). Play a game with someone. I'd think it would not take too long to ID the sounds b/c they are very different.

Having to count cash drawers as part of my occupation I have developed a counting method that is by sound. I will count the coins as they drop leaving my eyes available for other things. Many a silver coin was detected by the difference in sound they make compared to clad coins.
Good practical use. It amazes me how many people cannot name who the people's likeness is on the OBVs of our coins let alone how to count them by sound.
