acid treating

well first off let me say i do not but them. but i have several buffalos with no date and im debating on what to do with them. is the acid for them something you can buy, or do you have to send them somewhere to get it done, i would like to get the dates on these and sell them, cause there is a market for them , thanks rich

thanks for the info, yes i know there considered damaged and i will state that, and you can definately tell when its been treated. im only looking to sell them to peopl looking for filling a hole, i just cant see throwing them out, thanks again, rich

 

Actually you don't have to throw them out or treat them with acid. Try selling them as is on EBAY. You'ld be surprized at what people buy there. Just advertise Buffalo Nickels with no dates. I had a roll of them once and gave them to a coin dealer I know for face value. He turned around and sold the entire roll on EBAY for over ten times face value.

 

yeah i have seen that also, its amazing one what some people with buy

 

They're used a lot in Native American silver and turquoise jewelry,bracelets,necklaces etc....no date needed.
Here's an example.

Nitric Acid

I hear there used to be a product similar to nic-a-date for the purpose of restoring dates on silver coins. Anybody know what the name of that product was and/or why they stopped making it? I also read that Nitric Acid can be used to restore the dates on silver coins. Where do I find such a date-restorer, and how do I use it safely? Thanks.

 

Hopefully, nowhere.

Safe for you, or safe for the coin you plan on damaging beyond it's hard-earned wear?

 

Know anyone in High School or college? The chem labs all have that stuff. However, using it if you don't know what your doing could cost you your eyesight.

 

well i got it in the mail today, used it and works good, its amazing on what it does. i did not find any keydates

 

I wouldn't use nitric acid on silver coins unless you like nice black coins. Silver an nitric acid forms silver nitrate which turns black upon exposure to light.

 

Thank you Mr Mathew Brady!

 

Dude, WHERE did you get it from? I had some once and got some dates back on a couple of common SLQs. Now I am looking all over and cannot find it. I think it was a 3% solution.

 

If it is nitric acid you used, WHERE did you get it? I had some and found dates on SLQs, but used it all up. It was a 3% solution if memory serves.

 

One more thing about Nic-A-Dated nickels. Since they are now technically culls, a good way to get the black junk off them is to dip them in Tarn-X. I know that's taboo to coin collectors, but at this point it won't really hurt anything. I have six 1913-S Type II Buffs that are clean now and readable. So is my 1918/7-S. It seems to keep the acid from continuing to erode the treated ares.

 

Nitric acid is available in most chemistry stores, although it is pricey. The cheapest may be a small bottle of nic-a-date. I have it for mixing aqua regia. I think I paid almost $80 for a gallon at a retail chemical supply store. This is also pure (I forget the percentage in solution) - and will continue to eat the metal aggressively. Best to use the nic-a-date and not a home brew unless you have a good chemistry set and safety measures in place.

 

Dang! I hope we didn't pay that much. They used to deliver it 3000 gallons at a time.

 

Wow man, that's a lot of acid! (Tommy Chong flashback!) No, I'm sure the majority of the cost for me is because it's a small quantity, and since it's a dangerous chemical, they have to document sales, MSDS and compliance stuff. I am a hobby/end user - and they generally hit us for a premium on things like this.

 

I noticed. I checked on Grainger. You actually got a bargain.

 

How did you apply the acid to the SLQs ? I'm guessing just a drop or two on the date area.

If you ever find anymore of the silver coin date restorer post it please. I have one silver Sicilian coin that I would love to restore the date on.
