As a few of you know, I am currently working on a new book about coin cleanings. Here are some of the pics that will be included. Hopefully all will walk away with some new knowledge. Download Attachment: Half Cent /a cleaned.jpg" target="_blank" rel="nofollow">  1828 Half Cent cleaned.jpg 48.03Â KB Notice how the lines cross over the devices. This coin was dipped also. Download Attachment: Buffalo nickel /a abrasion cleaning.jpg" target="_blank" rel="nofollow"> 1936 Buffalo nickel abrasion cleaning.jpg 53.4Â KB This is a weak form of whizzing. This nickel was cleaned with a harsh cotton rag. Download Attachment: 1988-P Lincoln Die Prep 4.jpg44.44Â KB This is a Lincoln Cent with die polish lines. Note how the scratches DO NOT cross over the devices. Many will assume cleaning and pass up an interesting coin. Download Attachment: Counting-Machine-Damage.jpg40.58Â KB A neat form of counting machine damage. Note how it only effected one digit in the date. Download Attachment: Lincoln Cent Fingerprint.jpg 56.42Â KB Self explanatory Download Attachment: Lincoln Cent Rubberband toning-wiped.jpg 58.49Â KB Rubberband toning is one that is easily detectable by most dealers. Suffer is another trick used to darken up cleaned or dipped coppers. Download Attachment: Lincoln Cent copper abrasion.jpg 37.03Â KB Another easy one Download Attachment: wiped area.jpg53.53Â KB Another wiped coin. You can easily see the wiped marks across the fields. |

I have 100 coins undergoing various forms of cleaning now. Once these coins are finished, I will write small descriptions and provide close up pics and overall pics so that everyone can see how to spot these. As far as who will appreciate it, well if one person learns from my efforts, I am satisfied. I have found quite a few participating in the forum that are willing to learn. So I will continue to share.
Thank you for saying so. I certainly appreciate knowing that someone cares to read what I write. Makes the time and effort worth it.

I always find your posts informative ND and appreciate the things you do to teach us. I will have to admit though that I do not look at coins close enough to detect some of these cleanings. Under magnification they are easy to see, but are they just as easy to the naked eye?

Most can be seen with the naked eye if you know what to look for. That is why I am working so hard on this. Most collectors have no idea of what "tell tale" signs to look for. Now some original coins may exhibit the same characteristics, but it is far better to pass on one original coin than to be burned on one bad one.
Speedy, I will update anyone that wishes to know by email. Even though it may be allowed to self promote here on the forum, that is not my intention. For now, I am looking for late fall. If the publisher doesn't make it a cook book before hand.

ND, will you be addressing other forms of alteration in addition to cleaning, e.g. dipping, whizzing, polishing?

Absolutely. Wiping, swirling, rubbing, whizzing, polishing, dipping, acid treatment, acetone, coin solvents, and a few others are all going to be coming up in the next couple of weeks. I want to have one thread for each type of cleaning so that it is easier to update.
Also, if anyone wants a hard copy of all the pics and info on the coin and its preperation, just drop me an email about which process. You will have to cover the postage though. Each process is several pages and plenty of good pics.

ND,I finally got a chance to look at the pics. I have a couple of questions. What exactly are "rubberband" and "suffer" toning? How are they done? Also, I know you don't want to self-promote, but I would definitely appreciate it (as I am sure other members here would also) if you posted here when the book is finished. I don't see it as self-promotion. A book of this type would be invaluable to all of us. I know I am anxiously awaiting its completion.  |

If you grind up rubberbands they will darken copper coins in about a week. Sulfer is from ground up match heads. This has basically the same effect. Both will work on silver but often turns them very dark. It is used to hide minor bag marks and old cleanings.
I will keep the members here updated on the progress of the book. Currently, I am suffering through a strong bout with the flu, so my time is a bit limited.

Hi ND, Hope you feel better! If your infuenza symptoms started within the last 48 hrs there are a couple of medications which can shorten duration of illness- pm me for questions. If its past that time period get lots of rest, sleep and stay hydated! Looking forward to the book and more info. Did you see these pics at CU?: http:// (046) Not Allowed - Auto-Removed &threadid=294207 Don |

It would seem to me that ground-up rubber would leave an almost sticky-type residue on the coins, making this an exceptionally bad idea. |

Speaking of cleaning, anyone else seen the Tarn-X commercial where they're dunking a coin (looks like a Peace dollar?) in that stuff? I want to scream every time I see that...  Rachel [:p] |
