EBAY SELLER, AT COINS!

If you're writing a program to search listings, eBay lets you set up a "sellers to ignore" list, with a maximum capacity that I forget (100? 500?). It is a shame that you can't do this in Advanced Search on their site. I've been meaning to build my own search tool for a while now, but I rather doubt I'll ever get around to it. It sure would be nice never to have to wade through another spam-burst from edynamicmarketing, gti2, heartdr4u, eternitycoins...

Most of the ATs of al the denoninations are "artistically created" and actually the entire coin is die stamped in China as their laws permit it BUT if anyone in China makes a Chinese fugazi they will end up under a Chinese Tank or worse. There is a counterfeit ring in Hong Kong and Nanking and USA coin and currency is there specialty.
Personally I think a well aimed JDAM would solved the problem IMHO.

There will be nothing done about China counterfeits until the US makes it a higher priority than occasional lip service and raiding dealers that are quickly replaced by more dealers.

 

I've thought about this as well, either a web app or a desktop app. You can exclude sellers in Advanced Settings for your saved searches, but it does not pull through to the iPhone app.
I've also wanted to write something to iterate through all Great Collections listings and output a file of listings that contain TrueViews.

 

The intense feelings some folks have against TONERS makes me think they want the Pro-Toners to wear scarlet Ts on their forehead and do penance when the Toned coins have been here before all of us Circa BC, I might look good with a T on my forehead right next to MOM, Ha.
BTW Id like to see your Ts !!

You can? All I can see is an option to limit the search to a specific seller or list of sellers, which is sort of the opposite of excluding them. Where do you see this option?

 

I need a expert opinion on this 1893 S Morgan as it has some damage, Grade

 

Jeff,
What I meant was IF the Photo is a good one (DSLR camera) and the white balance is correct my Newport spectrometer and Computer combination can detect AT from NT from the refracted light of the coin in the photo.
This is similar to what PCGS and NGC uses to "sniff " coins their term not mine.
The same equipment is used by astronomers to determine what stars are made of and how fast they are mov ing (Red and Blueshift Etc.) solely from the light (Photons) that are visible between ultra-violet and infra-red which is the visible spectrum as measured in angstrom units.
Does this help ??

The word "include" for the eBay seller name is in a drop down. You can change it to "exclude".

 

You are way more advanced then I am for testing it. I really just give it the eye test and in all honesty I have kind of stopped caring whether it is AT or NT and just started caring about whether or not I like the look. There's really no way for us to tell definitively what was helped along and what wasn't and as long as things aren't being applied to the surface of the coin like chemicals to tone it or extreme heat in an over I consider it natural since nature was the one that did it by just leaving it where it was. I don't really understand how we praise album toning from something sitting in there but we will bash someone if they figured out their window ledge leads to great colors.

 

Where do I send your check?

 

It may simply be a matter of intent. I don't think the dealer who inspired this thread is depending on his window ledge.

 

The main reason is to enjoy the coin, I do collect but my BIG " a ha gotcha " is a lot of fun when I find a AT selling for 1000% over Redbook, a lot of my fellow Marines send me pics on their cell phones when their at the auctions and before they make the purchase, They tell me 10-15% of the dealers are selling these and my track record is about 80% ID ing the ATs, however if they like the color and the price is no more than 10-15% above book they buy the coin if (MS+ Grade)
or DCAM 67s. I have attached a chart that may help and follow the precedence of color, good luck

"IF the Photo is a good one (DSLR camera) and the white balance is correct my Newport spectrometer and Computer combination can detect AT from NT from the refracted light of the coin in the photo."

The light coming into the focal plane image is reflected rather than refracted. If I took a 'perfect ' photo of an emerald I could not detect if it contained Vanadium, the light would have to pass through the jewel to the spectroscope.Light from stars is emitted from the star, and refracted through the spectroscope attached to the eyepiece of the telescope to indicate the star's components from spectral lines formed by the level of energy change as the electrons jump shells or quanta ranges. Perhaps if you could heat a coin to incandescence with out destroying it, you could detect the surface compositions. Jim

 

Not to mention there is no difference - to a scientific exactitude - between artificial toning done right and natural toning.

 

It helps me understand what you're saying, but I can't see how it can possibly work.

Spectroscopy relies on detecting differences in light that's reflected, transmitted, emitted or absorbed, according to its wavelengths (color). A spectroscope can distinguish hundreds or thousands of millions of different wavelengths; by seeing how their brightness compares, you can learn something about the material that you're examining.

The problem with a photo, no matter how good your camera, is that it muddles all these different wavelengths into three bins -- red, green, and blue -- and just records how much light falls into each bin for each pixel in the image. It doesn't record detailed wavelength information at all.

Trying to do spectroscopy from a DSLR image would be like trying to time a footrace with a sundial. I just don't see any way that you can get the information you need out of a photo. The best you can get out of your spectrometer, no matter how sophisticated it is, is a measurement of your display's red, green, and blue emission spectra, weighted according to how bright each of those three channels is at the pixel you're examining.

 

This star comparison was just used to illustrate an example of how photon spectrometers work and NOT how I use it with toned coins. What I did not mention was the Order of the coloration as illustrated by the sunnywood chart and this order of color especially Series 1 and 2 is the criteria that is used to determine reasonable authenticity. I get the best results using a slit size of .5 mm and sample the color data from top to bottom of the coin image about 100 passes similar to a MRI. The brightness is mostly irrelevant and the accuracy is 4.1 pixels/2.5 ang. units
The coloration varies with the type of Coin Morgan, Peace, Halves, Etc. and I use the Sunnywood Collection shown on PCGS and my own collection of Toners as my comparatives and baseline. I believe the results are somewhat subjective but have found them to be 70-80% accurate detecting Fugazi toners. nuff said ??.
I am going up north to fish and drink beer for a couple of weeks and will put up some pics of my work when I return and by the way light is refracted from the toned silver and being old school I like sundials.

Rick Tomaska apparently just sold one. Or maybe he realized it is AT and removed it.

Understanding this is an old thread can someone tell me if 'gti2' seller on ebay is doing hat? selling salted in fakes from china or what?

He has an ad stating that he has 106 coffee cans full of old searched coins from his grandfathers hoard. Very doubtful of course AND the price is $235 for 2500 coins or just shy of .10/coin.

he has been largely ignored bc i see there are 9 lot available (ad had been up for a while).

What's the deal? Have you guys figured out what this guys scam is?

Ebay title:
"Eliminate the Middleman - Old Coffee Cans with 2500 Mixed Lincoln Wheat Cents"

 

It doesn't take Mr. Holmes to figure out what this clown is up to. Do you really think this is how dealers acquire inventory? The guy is telling tales about all these coffee cans of coins and shows a bunch of nice photos of them, but for some crazy reason buyers do not get the actual cans with their purchase? Come on....

There's no great secret here and the guy is simply trying to appeal to the very human desire to get something for nothing. Sure, scores sometimes do happen, but they're not going to magically fall into your lap on eBay. If you want to find them you're going to have to get out there and beat feet, and even then you may never stumble upon anything significant or truly profitable. Basically, you would be wise to avoid this type of nonsense as if the plague and instead invest your efforts into learning.
