CoinCare for copper?

lincolnSence

Does anybody have any experience with a product called coincare? Specifically if someone used it on say a lincoln cent to remove PVC would this have any effect on the color, the PVC, the skin, luster etc? Thanks.

I'm not sure, but dipping copper coins will ruin them.

littlewicher - thanks but I need a better answer to this one.

You are getting the best advice you can get from wicher - don't dink with copper unless you really know what you're doing.

Copper is one of the most difficult coins to control. They're so unpredictable. To tell you the truth, don't mess with copper at all unless you are positively sure what you are doing. Your best choice might be using NCS to conserve your copper coins.

Use acetone for the pvc.
Olive oil bath for a month for crud. Then chew on a toothpick until real soft and use the softened end to work away the crud.
Blue Ribbon Coin Conditioner to protect the coins surface.
This Blue Ribbon is no longer being made but is still available on Ebay and at many dealers.

face it, a lot of copper has pre-existing problems. none of the products mentioned are 100%, or even 80% sure-fire solutions, BUT, next time your at a major show, talk to tom reynolds, or any of the other big copper guys. i've tried before, mixed results.

copper can be dipped, but there is a gotcha. i won't reveal the secret here, since i don't want to be responsible for likely problems, but again , talk to 1 of the big boys.

remember: you didnt hear it from me!

Try WD40. Not a joke, try on some cheap cents and check out results.

thankyou all but I need to know specifically about this product. It was used on a coin and the dealer has suggested its PERFECTLY safe. It was used to remove PVC supposedly. Thanks for the current methods however, I'm really not cut out to be a "doctor" - although how much does it pay? Only kidding!

Placid

It's made by the same company that makes MS70.
I would try it on a couple of common copper pennys to test it out.

You might contact this place and see if they can get you some information.

Lincoln sence - Coin care is a greasy product that is used to protect copper.It can only be used on Brown copper.It will eventually turn red copper brown.It can be removed with acetone.

Are you aware that the $#%&* 1959 wheat back cent that is being sold (or will not be sold) at the Goldbergs auction had PVC all over the coin.Coin care was put on with a Q tip and miraculously the coin went from AU to mint state

if you bathe in olive oil, will you
1)get rid of environmental damage(turn a blackish color to brown)?
2)be harmful?

dorkkarl

ok, i will state this: coin-kare IS safe for removing PVC.

oh, and olive-oil is also safe. takes a LONG time, thought, we're talking months, not seconds or minutes. (DO NOT try w/ silver , though.) will not turn "black" to "brown". if your copper coin is "black", you are stuck, do not attempt to "fix" it, and sell it for what it is.

I'm not sure but I believe Coin-Care is the new product that was made to replace Blue Ribbon. If so it is probably safe at least for brown copper. Blue ribbon was a silicone based oil dissolved in 1,1,1 trichlorethane. That solvent was judged to be a an ozone destroyer and the EPA banned the solvent. Coin-Care is probably the same oil with a different solvent, probably Xyllene or Acetone. The solvent removes gunk, skin oils, and build up from the coin and leaves a silicone oil film on the copper to protect it. Sometimes it will slightly darken mint red coins. It will also often remove the color from cleaned and recolored coppers.

I have yet to find anything that will "clean" the copper. Olive oil can be used to dislodge crud but must be changed frequently becuase it turns rancid. Mineral oil does not turn and does as good of a job. MS70 turns the copper pink and the grading services will body bag these. The carbon spotting so often found on copper is actually IN the copper (i.e. it is not a surface blemish). Bottom line with copper is, IMHO, leave it alone!!
