Thanks for the cleaning advice on silvers. I think one of my coins has already been experimented (me? right) my US half dollar. Before sought advice from the community I had soaked overnight my coin in coke (s/drink) then the next day in vinegar. I have some pics below if you can advise me if yes my coin is messed up or whatever? Is it worth anything? Etc etc.  http://www.coincommunity.com/forum/...ollarobv.jpg target _blank rel nofollow  Halfdollarobv.jpg /a br / 97.51 nbsp KB" border="0" style='cursor:default' onClick='doimage(this,event)'> http://www.coincommunity.com/forum/...ollarrev.jpg target _blank rel nofollow Halfdollarrev.jpg /a br / 101.15 nbsp KB" border="0" style='cursor:default' onClick='doimage(this,event)'> |

Well, Davidson, you can't really tell by the pics, did you rinse with distilled water after your "treatment?" I don't think coke and vinegar should really be used on coins. But, I'll let the experts reply.  |

The good news is that the coin is 90% silver and will always have value from it's silver content. This common date coin was not in great condition before your experiment anyways so it's wasn't worth more than melt therefore, you didn't lose much value.
Just don't do it again :)

Vinegar is dilute acetic acid and prolonged exposure to it will damage coins. Coke is likely acidic as well due to the carbon dioxide dissolved in it which forms carbonic acid. Acetone can be used with care but the best rule of thumb is not to try cleaning your silver coins.

yes dont do that again :)...However though it has carbonic acid the thing thats more damaging is the phosphoric acid. Anyone from the South knows you can clean corrosion off a battery with coke. Also if you leave a pork chop in coke it will be gone in three days(not exactly sure how that one started but ya know)

Don't clean coins ever! Unless they have 3 inches of road tar on them. At that point, they are worthless anyway.

When I was a kid my Dad had a gas station and when they changed tires, if the tire wasn't easy to get off they would pour Coke near the rim and let it soak for a while. Then it came right off. And true it used to be used to clean car battery posts, rust on anything, kill weeds, etc. But for cleaning coins it is not the best thing in the world. Did those dark lines come from the cleaning attempt? |

Interesting, so is drinking coke safe? I don't think I will ever see the coke the same way ever again...  Edited by hc8604

Seeing that the coke goes into the stomach which has the pH of battery acid if food isn't present, there is no problem with the acid component. Besides the acids in soft drinks and vinegar ( acetic acid) are "chemically weak" acids, meaning that relatively few H+ acidic ions are released compared to HCl or sulfuric acid.

But I heard that if you put a cockroach in a glass of Coke, sealed it up and left it overnight that the next morning it will have completely dissolved it. You can also perform a car battery protection service by pouring Coke on your battery terminals. Also, I am drinking one right now. Scary, no?
Given all that, I can't imagine soaking a COIN in it. YIKES!

Why is it always Coke mentioned? The pH of coke is almost exactly the same as Pepsi when we measured it in a lab experiment. Salsa has a ph of about 3.5, so maybe a salsa dip for that morgan  Jim |
