I know there's at least one TPG that will slab acid-dated Buffaloes (details, of course). And restored key dates still trade at a premium to common dates, just like details key dates in any other series.
The Inspector’s specimens were put into a vinegar and hydrogen peroxide solution. I prefer this over the acid drop over the date or mm. The coin will be etched all over but I prefer the even etch over the localized etching.
Again, you don't even need the peroxide if you're willing to be a bit patient (soak for a few hours or days).
Thanks for the input. I’m almost a 99% collector. I almost never buy a coin with resale in mind. To me the fact I have something unique is of more “value” to me. I liken using Nicadate to scratch off lottery tickets.
That's a great analogy - it's cheap entertainment. Except that a "losing" Buffalo nickel is probably still worth at least what you paid for it! And it's harder to spend yourself into financial trouble on dateless Buffs...
Yes Inspector. Here’s what I’ve learned with the white vinegar/hydrogen peroxide mix. 50/50 - results are fast but a more coarse etch. When using this, you need to be watching your coin. It could be etched in just a few minutes. 70/30 - This is what I’ve used most often. Etching takes longer but a smoother finish. I tend to reuse this solution so as it weakens, the etching takes longer but gets smoother. Used solution or straight vinegar give the better finish but takes longer. I also etching vertically to reduce the chance for a trapped bubble. in the end it’s destructive but fun to find out what is passing through our fingers.
