Worn-off dates on Buffalo nickels... a new idea?

Although maybe not the favorite, it is entirely possible that the increased density could have the higher heat transfer that matched the higher capacity. Translation is that both would heat at the same rate and you could see nothing.

FWIW, the denser material would, undoubtedly, have the higher heat capacity and my gut says it would also have the higher transfer rate since the atoms are closer together.

The difference is that vinegar ( acetic acid component) is not as specific for the copper material in the alloy as the Ferric Chloride solution in Nic-a-date. I do not recommend either as usually there are limiting environmental regulations as to disposals.

 

Think for a moment what you're doing these to. These aren't the Crown Jewels. Let's try to not lose sight of that.

 

Not gonna put vinegar on my jewels!

 

Sounds like you have another obsession besides coins.

 

Hey, me too. Same other obsession.

 

And here my friends are the results.....

Acid and coins don't mix...... but this is a complete set of Buffalo's . Any takers? This set was put together as a scout many years ago. But will admit they are a sorry set of Buffalo's .

 

Love the toning on that '37-D !!! Coin of the decade!

 

And if you soak the whole coin they don't look that bad. Better than nik-a-date coins do.

 

@Conder101 , how long would you soak a dateless Buff?

 

Adding a pinch of salt apparently helps. Time wise, vinegar is relatively slow. See https://www.cointalk.com/threads/nic-a-date-test.28021/page-3 They reported times from a few hours to 6 days.

 

Remember through your not going to have any skin left on them.....if you saw 90% of what I posted above in hand you would see that there no skin left on them. Yeah you can see the date but the surfaces are rough .

 

Not trying to be cute but......until the date appears, or the coin dissolves completely.

True but a whole coin soaked in vinegar, even without a skin, looks better than the ugly splotch on the date area of a nik-a-dated coin that has just had the date worked on. Or the weird colors seen on a coin whole soaked in nik-a-date. The other advantage to the whole coin vinegar soak is it also tends to restore other details as well.

 

I'm a old vinegar soaker from way back. Vinegar will leave those ugly splotches too or at least an outline if you spot clean with it. Definitely soak the whole coin. It will have a smoothed out look to it when finished. In my experience if you have to go over a week the date is a goner. One to three days usually has turned them up for me, mint mark, too, if any, at least enough to make them out. Hey, FWIW...
