1. Post a front and back image of your coin with a specific question about what you’re seeing or asking about and one coin per topic.

2. Please remove coin from the holder unless it’s US or an official mint case or unless it is graded by a grading service.

3. Images should be taken by a camera or cell phone camera, we ask that members don’t use images through a microscope screen.

It works most of the time but it damages the coin forever, it's like acid etching.

Yes - the acid work. I speak from experience. But it also leaves a stained area on the coin. The concept is that the letters of the date were compressed into a tighter density when the coin was stamped. So the acid eats away the less dense metal surrounding where the numbers were.

There is a guy I have seen (yoube I think) who restores buffalo nickels with chemical etchant. These sell on eBay as restored nickels.

Standing Liberty quarters are silver. I do not know of anything specifically made that will bring out the date on these. While the acid would "eat" them, I am speculating the silver is "dissolved" too quickly for the date to show though (someone please correct me if they know for sure).

There has always been discussion whether or not a dateless buffalo is better than a damaged one where you can read the date. When it comes down to it, a dateless buffalo is not worth much and neither is an acid etched one.
