Quote:But look at dateless Buffalo nickels that have their dates restored. Key dates for those do have value. But I think this is different from a restored Buffalo, since once you acid restore a dateless Buffalo, you can always see the date. As I understand this method, the coin becomes dateless again after it dries, so it no longer looks like a key date. |

So if you were to wet the coin again that dried out, you would be able to see the details again. Personally, I'll take that vs a permanently dateless SLQ any day.  |

I would try some different dilutions of the solution. You can probably hit on one that will allow more selective etching of the silver which would allow the date to be seen when dry. It will change the amount of time required to bring out the date though.
You note he says it only takes 30 seconds. It is probably attacking the entire surface very quickly and there is very little differentiation between the date and surrounding areas. That's why it needs to be wet to see. I'm thinking a more diluted solution may give it more time allowing the etching to proceed to a greater extent on the softer areas and allow them to be more visible.

How would a TPG respond to an alleged 1916 sent to them for grading if this discussed method was the only way that the date could be ascertained? In the end if the TPG validates the existence of a 1916, would they even slab a coin that would appear dateless in a slab? |

55 or 60 years ago date restorer was sold for dateless SL quarters, packaged the same way and sold by the same company that sold the nickel date restorer.

I'm glad someone else besides me remembers the date restorer for silver coins.

I purchased a tube of "Silver testing solution" which is a mix of nitric and muriatic acid as soon as davidb made his post on the thread. Did some testing with it soon after. Worked like magic! I varied the time a little bit. The sweet spot seemed to be between 30-45 seconds. I did not test further than 45 seconds. I originally did 20 seconds on the first few, but they were coming in weak. So I put more acid on the coins for another 10 seconds to test and it made the dates much clearer. Here are a few of the resulting coins. -DISCLAIMER: All of the coins were completely dateless before. You can also see the dates while the coins are dry. 1920 P  1920 S  1919 S  1918 S  |

Very nice ty88ty2!
I bought the silver testing solution as well. I'm just waiting to come across some dateless silver coins. I'm just wondering if I should do the entire coin, not just around the date. This will make the chemical reaction spot around the date less obvious.

Looks like I need to go find my dateless SLQs and try this! I have a number of D and S mintmarked dateless SLQs.

The original posting is about 18/17 die markers on a dateless specimen. I personally don't know the coin well enough to comment on the die markers, but I am very eager to hear if anyone knows the die markers or landmarks. If so, we should not attempt to restore that coin, because you can get a dateless SLQ certified if you can educate the grader(s) at a certified company on the die markers.

An easy one to spot, or cross off the list,,, is the 1917 type 1. The differences in her hair are easy to see even on worn coins.
