Although it would probably take longer due to silver being less reactive, I would think it would still have some effect. I have one candidate that I might try- a dateless young head Vicky threepence from my junk silver box. Report this Post to the Staff

I have had some thoughts of doing this as well for dateless SLQs perhaps, but I don't have enough of them to try and I'm a little afraid of the stronger acids you'd need to use to etch silver.

If that doesn't cause any changes then I would try ferric nitrate with a very small amount of nitric acid. Vinegar would do about as much as water in the way of etching the silver-copper alloy used.
