Huh... That's interesting, I didn't expect that to work at all. I am surprised as well. Interesting. I would not have taken the risk. |

The toning on the nickel is pretty nice as well.

acetone will not remove toning but it can remove the haziness that is caused by the material the proof set housings are made of. It will not harm the coins surface at all like ezzest or other dipping chemicals do where they remove part of the metal and can cause the coin to look lifeless because of taking away material. Just be sure you rinse the acetone off well and pat dry if you must only, never rub a proof coin because their fields are very easily scratched

I disagree with rinsing afterwards. The acetone (assuming it's pure acetone) should evaporate completely and should not need rinsing with water. Rinsing will leave water on the coin, which is bad. In fact, if I had to get a coin wet for some strange reason, I would use acetone to dry it back out.

 If the acetone is pure, it will always completely evaporate in seconds. It is advisable to do a second rinse in fresh acetone. This will ensure that whatever was dissolved by the first rinse of acetone will not redeposit onto the coin. |

What about mint sets? I got some in that look like they are smeared with a dried grease. How do I get it off? Same way?

As said, no need to rinse acetone. Though I have to add my surprise that it removed any of the haze. Tried it many times and got no results. I would also add that a quick dip in Ez est would be fine to remove the haze. IMO/E you would have to leave a coin in the dip for well into the minutes for it to kill a coin as mentioned. I have done it with circulated proofs and even after a solid minute there was no noticable difference from before the dip.

NCS can remove it. Dunno if they use something like ms70 or verdi-care.

These are all coins from the 60's and 70's. Do you think it would be worth it to send to NCS? I don't expect any to be high grade coins and would only have them conserve them for me. I just want my coins to look nice in my collection is all. The price really doesn't look too bad for the work, but they are all rather common coins.
I used acetone on almost all of my proof coins today with great success for the most part, but the unc's I have out of the mint sets are another thing all together. I am letting them soak over night in acetone to see if that helps. If not then it is either NCS or replace them. Most of them.

Sounds a wee bit dodgy to me  Especially when these are the people that slab the coins and make the grading decisions on that coin. |

There is cleaning... And there is conserving.
Having worked at a museum for a while I really can appreciate good conservation skills, although sadly many people employees as such often can do more harm that good due to competence, or lack thereof.

Ok, the acetone didn't work on the business strikes at all really. A couple that were cruddy got softened up some but they are still smokey looking like they have dried smeared on oil on them.

Like I said, I have no interest in getting them certified.
