As stated above, if the dipping is not 'detectable' it is generally acceptable... Best used to eliminate dirt and accumulated grunge....though sometimes used to eliminate tarnish....Cheers, RickO
Generally, it is frowned on. Occasionally it is purposeful. PCGS sometimes uses it when conserving coins.
Good advice is to avoid an acid dip if you don't know what you're doing or have no experience with it. Many coins have been spoiled by it. Some have been rescued.

All dipping that cannot be seen as dipped after the fact is acceptable. Any dipping that can be seen is frowned upon.
All comments reflect the opinion of the author, even when irrefutably accurate.
I've had a few customer only buy if I dipped it. I make them pay first.

I used to visit shop decades ago that would dip your newly purchased unc rolls in their special dip basket as a courtesy.
“Let’s get rid of that tarnish” he would say.
