"Jim" wrote in message ... Will it clean your coin? Probably not, but hey, people swear by olive oil, so who am I to say otherwise? You sound like someone who has tried olive oil long ago without any luck. Over the last several years, I have tried olive oil on dozens of copper coins, through several oil changes, and with minimal results on a small percentage of coins. I have seen a few small black chunks of something loose in the oil and determined that it wasn't dead bugs, so evidently something that has broke loose fromthe coin. OTOH, I set this copper token in olive oil and uncovered a deception; http://showcase.netins.net/web/bills...ns/HTT1837.JPG I seldom check the coins in the oo, so I do not know how long this token sat in the oo before the color started bleeding off, but I believe it to be less than a month, and it maybe that I had checked and discovered the bleeding within a few days. I do not know how many ways there are to darken a copper coin and I don't know if oo works for every way a coin can be falsely colored, but it worked for this one. Otherwise, I don't think oo is worth the effort. Bill |

The token came to me much different in appearance, a uniform dark brown. I wasn't suspicious of the tokens color, but after the color bled off, I do seem to recall that the brown token did look a little odd. Unfortunately, not being suspicious, I did not study the token to be able to have a sharp eye for other colored coppers. Bill |

I have had some success with olive oil on copper coins to get gunk off that
would not otherwise come off. It seems to take a while, but anything that is just laying on the surface of the coin seems to come off. I don't think it does anything to tarnish. Unfortunately, often when the crud comes off, you have a small part of the coin that is radically different in appearance from the rest of the coin because the gunk protected that part of the coin from wear. I did some experiments on some cheap coins once that had something on them. One was a British penny, I'd say G to VG, pretty worn with some black crud on the face of it. I tried rinsing it off, soaking in soapy water, alcohol, acetone, and maybe a few other things to see what would get this stuff off. Then I soaked it in olive oil for a few months. I was than able to lift the black gunk off with a toothpick, and to my surprise the patch of coin under the gunk looked unc, so the gunk must have been there for a long long time.

After the half has soaked in the acetone sulpher mixture a day, the Nickel
part shows no change. The copper part visible on the edge of the coin has turned pure black. Looks like I have a new pocket piece :-) Dale |

Question:
I normally (99% of the time) purchase high grade coins for my collection and rarely need to "curate" them. But, I understand that alot of people use the Olive Oil treatment and like it. My only question: is how do you get the residue off the coin without rubbing it off and creating wear? Fred "Dale Hallmark" dalehall.Not this wrote in message ...

The olive oil residure comes off quite well by rinsing most of it off with hot water followed by another brief soak in alchohol. Fred "Dale Hallmark" dalehall.Not this wrote in message ...

OTOH - I soaked a coin that had a lot of green crud on it in OO and a fair
amount of the green curd lifted off. It did not make the coin's surface come back any, but it did do something that made the coin look better and it did not harm the coin any. "Jim" wrote in message ... "Fred" asks..... But, I understand that alot of people use the Olive Oil treatment and like it. I would have to say, while politely biting lip and drawing blood, pouring down my chin, you are getting the wrong impression. Most people that have tried it, find.... 1.) Tediously long to show any positive results if at all. 2.) Those results are dubiously negligible if any and could be obtained by soaking the coin in any other material known to man. 3.) They are stuck dealing with the same question that brought you here. The same question that wants to make me reach out and go AAAAAAAAAARRRGGGHHHHHHHHHHHHHHHHHHHHHH............ ! Listen.......... Olive oil has NO, NONE, ZIP, NADA "curative" or otherwise powers to clean a coin. Never been shown to be "any more effective" than hominy grits, peanut butter or especially, a simple soap (not detergent) and warm water soak, followed by a distilled water rinse. But don't take my ranting word for it. See the proof from one of RCC's own. READ and return to dispel the gospel re olive oil, I implore you. http://tinyurl.com/tc0u AAAAAAAAARRRRRGGGGGGHHHHHH......
