KINDS OF COIN DOCTORING TO LOOK FOR

[MikeKing]

There are different kinds of coin doctoring at so many levels, and there's so much talk about it, the cac, the tpgs blah blah blah

 

But as collectors, can we KNOW all the tricks?

 

That's a really hard thing to do. It takes YEARS of practice (and getting burned)

 

So, I'm posting this, hoping for a sort of list or catalogue of the different kinds of doctoring, and if anyone has a photo, or no photo and just the knowlege, please post it.

 

e.g.,

 

Polishing (a recent post made me think of that)

Hazing (to cover scratches, marks, or even wear, in order to up the grade)

Puttying (again, coverup..and something I have a very hard time seeing)

Tobacco smoke (hazing via this method, or depositing enough tar that it covers corrosion or scratches etc...) (this is best done with a cigar)

I not only associate coin doctoring with trying to hide problems like you have stated Mike, but I also use the term for trying to conserve coins. Another type of doctoring comes to mind would be

Olive Oil- to help eliminate corrosion from copper.

Dipping- we all know what this is.

Thumbing is a known term for rubbing a visual anomolie by using the oils from your fingers to hinde the aforementioned spot or whatever

People used to wear early coins as a necklace by drilling/punching a hole through the top of the coin. These can be professional plugged so that it is very difficult to detect. Especially, as Mike mentioned in the other post on polished silver, it can be smoothed and then AT'd over.

Boogering: the art of taking nasal mucous chunks of a colored nature, and rubbing it into the bagmarks of a toned coin. The colored mucous will generally blend with the toning, making it impossible to spot. (this method usually works best if you have a nasty cold, or a toddler in the house)

 

Butt cheek toning: clamping the coin between some tight cheeks for a few days will give you a toning pattern that some like, as long as you can tolerate the smell. However, this type of toning usually passes muster with collectors, if it is already slabbed and the smell is trapped inside.

(look for someone that is very thrifty, they may be best to try this for you)

 

Trash Toning: This type of toning is usually the unintended result of your NEWP. Didn't tell the wife/husband about your recent purchase? You're awfully proud of it, but haven't seen it for a few days, have you? forgot where you hid it? It may just be in the 120 degree garage, stewing in the large black trash can where your spouse disposed of it after finding it. After a few days in there, it may pick up some nice color, but calling it NT may raise some eyebrows.

Introduction of obnoxious gas to coins surface, causing brilliant unnatural toning.

Whizzing...A techique in which surface metal is moved mechanically to create the illusion of luster.

duct tape & kraft paper toning

 

This one involves getting your hands on some post modernish kraft paper (manila colored) say from the 1950's-60's when pollution was allowed (sulphates used to process pulp) and wrapping the coin (both sides) with it and then taping it onto the inside of a window, preferably the one which receives the most sunlight.

 

Not only will the sulfur dioxides released by the kraft paper tone your coin, the heat from the sun and radiated heat from the windowpane glass will accelerate the process. This method works fine for 90% silver coins and is very hard to detect whether AT or NT. Remember, most NT will start at the edges progress inwards in bands, one where it has been accelerated, the tone will just sort of blend together.

 

Do not get any ideas…ya hear?

Someone told me that this can be detected if you weigh the coin on a sensitive scale since the plug plus sealer and polish makes the coin 3-4 grams overweight. Mark was once on the grading side, maybe he can help clear this up for me?!
