Spent most of the weekend reading, re-reading various posts on various forums on this subject. Candidate is a '66 Irish 10 shilling, which is about .650 I liked the test-dip of a 40% Kennedy better than a 90%. I saw no real difference in luster between the two. Is this your expierence? My test pieces were not heavily tarnished, but the Irish piece is. Some say acetone wont remove this type of brown "toning". What could I expect from giving this guy a bath? Or should I leave well enough alone?

Acetone will not remove real toning. I rinse all of my proofs with acetone before going into storage to removed all traces of moisture or light finger oils.

Toning, tarnishing, corroding, staining on coins is from a chemical reaction of the coin's metal and some outside substance. Acetone has little to no effect on metals so since anything on a coin from such a eraction is now part of the coin, not much should be accomplished by using Acetone. Quote:

Many people do this and it is really a decent idea. Always better to be safe than sorry. Although people think they didn't touch a coin, sometimes it just happens. |

Very interesting... I had no idea that people did this...
We're talking rinsing not washing/ cleaning, correct?

Just a fast dip to get rid of all the sometimes silly things that happen to coins. You touch it not thinking anything will happpen, you sneeze on or near it, you breath on it with and your breath has excessive humidity, etc. Things just happen. |

I use a rinse with a pipette on both sides, then on to a kimwipe, then immediately into an airtite.
As carl said, this will remove any "unseen" fingerprints, spit droplets, etc. that could damage the surface over time. I have NEVER put a coin into an airtite without first rinsing it with acetone.

I plucked a 1967 proof Canadian silver dollar from the local dealer's scrap silver bin this weekend, and was quite surprised to discover when giving it an acetone rinse, that the coin had a thin film of some kind of clearcoat, which the solvent removed quite readily. It actually looks shinier now, ready to acquire whatever toning will happen in its long term storage box.

Sounds like a remnant of the old thing people used to do to preserve coins. Some coated them with Shallac, Varnish, etc. True it preserved them but in time that coating got dull. |

Pure acetone will NOT damage ANY metal. End of story.
