^^thanks, just carl!
yup, I guess it is simple enough of a concept.
...still aesthetically, I like clean shiny coins better than if I just leave the grime on them...
Your not alone in that way of thinking. Probably millions of coin collectors clean coins. Way, way back if you collected coins and showed them to people, one thing you would usually hear is "why don't you clean those things, they would look so much better". And we did. This is why so many coins have been cleaned. An old Whitamn Folder with a lot of nice shinny pennies was something to show off back then. And today probably most kids in any chem class just has to see what acids do to coins. I wonder just how many people have spit on a coin to make it cleaner? Why what else is there to do with dirty coins? |

I started a thread on Classic US coins - "I'm ready to clean". In it I clean a copper coin. There are before and after pictures. |

I use toothpaste (colgate) to clean dirty silver coins and coins that have already been cleaned before.
For copper or brass I use eraser (rubber) to remove new finger prints. Just as an FYI that both of these methods will leave permanent hairlines on coins--easy to spot in a loupe or scope. I always look for such marks when I buy coins. It may be less of an issue if a silver coin is already cleaned--just my opinion here.  |

Both toothpaste and pencil erasers contain abrasives. Neither one of them should ever come anywhere near the surface of a coin  |

Indeed carl. This way of thinking also reduced the number of numismatically acceptable coins too. I'll share my tip: When I want "de-grime" an otherwise nearly worthless coin, I simply use a little dish soap on it and rub between my fingers under running warm water. Simple, effective and doesn't scratch the coin. However, the surface under the grime usually will leave spots. NEVER DO THIS TO A VALUABLE COIN. I've done it to Lincoln's just so I can make out the date. I'd hate to toss a 1909S VDB in the junk pile while searching wheats. LOL Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

If it can produce hairlines scraches on metal what more our tooth enamel? rubber also produces scraches on metal? I'll never use rubber again  Edited by manila galleon trade

The problem here is the same as with toothpaste or anything that is a solution of products. Seldom is it possible to find any dish soap with the same chemical formulae. Toothpaste even more so. The chemical composition of such products is varied massively as well as the type of ingrediants. And although many products list some or all of the substances included, practically none reveal the percentages. Such information is usually proprietary due to industrial formulae theft is a constant problem. The reason I mention this is an attempt to clean a coin with dish soap or toothpaste by one person may well have consideral different effects by someone else. One tooth paste or dish soap may contain substances that are actually dangerous to coins. Others may have no effect at all. Be carefull out there. |
