I should have been more descriptive. This cent has what appears to be green debris or dirt around parts of the date and I would like to clean the cent so as to remove what could be hiding a clue to DDO.  |

A good soak in acetone might remove some of that stuff. If it doesn't, you could leave it alone or if you're feeling brave, you could soak in acetone to soften that material then use a very small thorn from a plant (softer than copper) to gently pull the debris from within the letter

 and But I use a porcupine quill. ...eBay if you don't have road kill where you are. Also very inexpensive, the tips are very durable, very soft, and the longer shaft of it is easier to handle than a rosebush thorn How much squash could a Sasquatch squash if a Sasquatch would squash squash?

"But I use a porcupine quill."
What about the plastic toothpick from a Swiss army knife, or something similar in plastic that's been sharpened a bit more than that?
For that matter, a fingernail clipping might work. I tried scratching a silver coin I got that had been polished to an unnatural sheen, and I couldn't make a mark on it with my thumbnail.
But the quill sounds very interesting, and more durable.

So if you can't find a porcupine running around your back yard , just use the teeth from a mountain lion .  |

@Pauldog That is an interesting idea if you could find something that could maintain its strength while being sharpened down to the size small enough to scoop the gunk out of the inside cavities of a mint mark. A Swiss Army knife "toothpick" is way to large. To some quills, the inside of the 0 in the OP's pic would be a relatively large area. A fingernail clipping is a good idea also. But harder to manipulate. @T-Bop  https://www.ebay.com/itm/american-p...D0:rk:1:pf:1How much squash could a Sasquatch squash if a Sasquatch would squash squash?

I've seen porcupine quill earrings for sale at powwows and some shops. I could possibly track down a maker and buy a few quills, or trade a silver dime or quarter for some.
Or I could just get a "rescue porcupine" from the local animal shelter. Maybe this could somehow dovetail with the upcoming Groundhog Day. I could watch that movie with my new pet porcupine and groundhog. (This is starting to remind me of the old "Pogo" comic strip.)
I also noticed a piece or two of plastic that had gotten broken off from something, and of course I've got several kinds of plastic in the recycling bin. A polypropylene lid might do the trick, if sharpened enough. Polypropolene seems softer than most other plastics. I could test a few kinds of plastic on a silver coin I don't care about.

I hope the plastic can work. It might be able to last even linger than a quill. They do wear out after awhile by the point either fraying or bending when I apply too much pressure. It will take some micro sharpening though for sure. I need to sometime post some pics of using one of the quills so people can get a better idea of how small, yet sturdy that can be.

I ordered some quills and they should arrive soon. I will get some acetone. How long would you soak the coin or coin in acetone before taking them out.
Also, would you rinse then with sterile water or deionized water?
Thanks

The quill or plastic idea is a good one, but keep in mind that the "gunk" might be abrasive and the quill might rub some on the coin.

No rinse in water is required, if you soak in acetone it's best to let the acetone air dry from the coin.
As for soaking time, it depends on how thick/greasy the stuff is. Generally an hour would be more than sufficient

 Leave your coin in the Acetone for approximately 10 years.  Then rinse with Sulfuric Acid but be careful with that. A wire wheel on a bench grinder would help also. All just kidding. If you don't have to, don't clean coins. Yours is mostly just what may be Machine Doubling which is not the same as a double die coin. If you really want to clean it, just a few minutes in Acetone is about all you need. |
