Anyone Ever Use MS-70, Coin Care Or Nic-A-Lene?

I have a few very dark copper coins, especially in my Dansco 7070 Types album, that I would like to lighten up to be more visually appealing & enjoyable, not to resell. That's why I'm asking about these products.

And here is a little known advertised fact. Check your next can or bottle of beer. See if you can find the % of Alcohol.

What are you saying? That the % is not listed? Or that you can use beer to clean your coins?

Rub these coin cleaners into a coin, and it'll remove all of that grime and fingerprinting! And the mint luster, several layers of metal, the coin's eye appeal, some details, plus 90% of the coin's value.

biokemist,

I just read the threads you posted that discussed MS-70. Thanks.

Now, what about the other products - Coin Care or Nic-A-Lene? Any opinions on these?

As I said before, I have a few very dark copper coins, like Large Cents, Half Cents, Twenty Cents, in my Dansco 7070 Types album, and some Lincolns & Indian Head cents, that I would like to lighten up to be more visually appealing & enjoyable for myself, not to resell. That's why I'm asking about these products.

Any opinions on Coin Care or Nic-A-Lene or similar products for coppers?

I do not have experience with either one of those products. Nic-a-lene is made by the same company as Nic-a-date and it appears to be a detergent/surfactant mixture similar to MS-70 but I cannot say if the results would be the same. The Coin Care seems to be the opposite of Deller's Darkener. The Darkener would be an oxidizing agent, creating toning, and the Coin Care would be a reducing agent, stripping toning. IMO, that is way too much chemistry to be applying to a coin.

And the thing that's irritating is that people will dip almost any coins that they get their hands on, but then they when they're buying a coin for themselves they try to find original, undipped examples.

Sounds like dating & marriage. When people are dating, they want someone with "experience." When it's time for them to get married, they want someone who's never been touched.

Most chemical solutions to be used on a coin will do the basically same thing as Tarn-X type solutions or a good battery acid. Ruin the coins. If you find your Copper or Copper included coins are darkening, this is just normal Oxygenation. Note that the removal of this is actually removing some of the coins metal. Of course you will have a pretty, shinny coin, but you will loose most of it's value. Copper is in many of our coins as a mixture and that is the most reactive metal so it is the one that usually creates the darkening. If left alone, this CuO will usually further react with Moisture and Carbon Dioxide in the air creating more darkening and in some instances a Greenish Patina.
Again, removing these substances will remove some of the coins metal.
My previous statement about the lack of % on a bottle or can of beer was intended to show how a product we drink every day is lacking in complete ingrediants on the container. Note that some either water downed or made excessive alcohol content beers do list the % such as 3.2 beer

"I have tried MS70 on circulated copper (1970s Lincoln Cent). It came out with light bluish/violet hues"

Is that what happened to this coin? I've been trying to figure out how she got this way. You can barely see the colors inside. I took this photo outside in bright sunshine
