Oh you'll see both. I'll post them both here when they start showing dates. The nickel in all honesty might be ready by tomorrow.
I seem to recall being able to buy it in the early 1980s but that my B&M store refusing to sell it to me as I was 7 or 8 years old.
I can't get a picture of it because the date is faint. I still have it soaking so I'll post pictures when it is bolder.
It's just white vinegar. I thinks it's diluted 5% so that or a little higher concentration should be fine.
I have a dateless 19?7 walker that I would like to figure its date out on. I picked it up for $1 so it wont be a big loss if I kill the coin. :whistle:
Go for it. It's a fun thing to do, but you need to be patient. For example, I'm still not totally sure what mine is besides the S and the 19 (which I can't see) and it has been in there for more than 2 weeks.
And another thing: the vinegar actually brings back other details on the coin, like the LIBERTY on the Buffalo is completely visible after soaking. I like it more than nic-a-date because it looks more natural.
Please keep us informed on the SLQ. I have about 2 dozen dateless SLQ's and not really sure what to do with them.
Here's the result of soaking a dateless Buffalo for 2-weeks in distilled white vinegar. I changed the vinegar three times during this two week journey. In the end, I got a very light 1915. It is pitiful but readable. I've had luck with restoring the dates of several other Buffalo's using the same process. I will say that it is better to do each coin in its own bath. A few of the coins soaking in the same bath got some serious de-colorization. In the end, I was happy with the experiment though. I got a few 1915's, a few 1916's, and a few 1919's. I'm thinking that I raised the value about 10x, not that I much care for that.
