Does these products have acetone in em. I was told that fingernail polish remover or acetone will also work to bring the dates out on nickels. I cant find nic-a-date or coin date anywhere so would these items work also? I have 11 no date buffalos that Ive found that have mintmarks on the back that I would like to see what the dates are. THX

I don't know if coin date has acetone, but I have used it with Buffalo and V nickels with positive results. I bought it many years ago and it still works fine. |

You talking about coin date or acetone?

Acetone is an organic solvent and will only react with organic and aqueous material. It is useful for removing finger grease, pvc residue, and some other contaminants from coins but it will not react with metal. The commercial product Nic-a-date is composed of ferric chloride I believe(not an acid). Nic-a-date is carried by many online coin supply companies and I am sure it can be found on ebay as well. |

Nic-a-date almost has to have an acid in it. How would ferric chloride react with nickel? Ferric chloride is a salt, and not a very rective one.

I remember reading somewhere that nic-a-date is a diluted muriatic acid mixed with other things to make it thicker.
I don't reccommend anyone to use full strength muriatic acid without proper safety handling equipment

I am not a chemistry guru, but I have used coin date for many years with success. You dab it on for 1/2 a minute and wash it off with water.I have gotten many early date Buffalo nickels including the 1918d/8 over 7 |

Muriatic acid is the same as hydrochloric acid- very powerful acid and this acid alone does work well for restoring dates, though not quite as good as nitric acid. Both acids are very powerful, caustic, bruning. Should be used with a lot of ventilation, gloves, and some type of drop cloth should be laid out- I got a drop of nitric acid on my wooden table and it left a nice scar on the table.

Ok, I have done some exhaustive research on Nic-a-date, or more appropriately the active ingredient ferric chloride[iron(III)chloride], and why Nic-a-date works on nickel but not copper, silver, or gold coins. It involves oxidation states, reduction potentials, and redox reactions. I am going to place all of this in a separate post because it will involve alot of chemistry but I will try to explain as best as possible in plain English. It will take some time to create this post so it will probably go out over the weekend. BTW, ferric chloride solution is not an acid per se, but it is an acidic solution and is corrosive but weak compared to strong mineral acids like hydrochloric, sulfuric, and nitric acids.
