Is There A Way To Tell On A Dateless SLQ If It's A 1918/17?

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

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.

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.
