There was a trick named soundproof coins that was some sort of liquid you applied to your coins to have them not talk (I assume it also came with a routine). It looks to be sold out everywhere I look. Is this something that may be coming back? I’d love to get my clad coins to quiet up!

If you aren't going to hand out the coins, try clear packing tape. Completely soundless.

CS Hyde Optical Clear Teflon tape too.
Not as cheap as packing Tape, but you will be able to do 3 fly with any type coin and not talk.

Cheers!

How about practice?

There is a clear, silicone rim I have seen on Penguin and The vanishing...some people love it.

I have tried rubber cement and other surface changers, and found that YES they muffled the sound, but changed the behavior of coins.

You may want to consider some palming coins (available on amazon). The Morgan’s are particularly good (I have 20 of them). They are not completely noiseless, but they are LESS noisy and work very will for misers dream, coins through table and my “four fly” (three fly plus one) routine.
